+ * This method can be used to change which mocked responses `$httpBackend` returns, when defining
+ * them with {@link ngMock.$httpBackend#when $httpBackend.when()} (and shortcut methods).
+ * By default, `$httpBackend` returns the first definition that matches. When setting
+ * `$http.matchLatestDefinitionEnabled(true)`, it will use the last response that matches, i.e. the
+ * one that was added last.
+ *
+ * ```js
+ * hb.when('GET', '/url1').respond(200, 'content', {});
+ * hb.when('GET', '/url1').respond(201, 'another', {});
+ * hb('GET', '/url1'); // receives "content"
+ *
+ * $http.matchLatestDefinitionEnabled(true)
+ * hb('GET', '/url1'); // receives "another"
+ *
+ * hb.when('GET', '/url1').respond(201, 'onemore', {});
+ * hb('GET', '/url1'); // receives "onemore"
+ * ```
+ *
+ * This is useful if a you have a default response that is overriden inside specific tests.

- * @ngdoc service
- * @name $compile
- * @kind function
- *
- * @description
- * Compiles an HTML string or DOM into a template and produces a template function, which
- * can then be used to link {@link ng.$rootScope.Scope `scope`} and the template together.
- *
- * The compilation is a process of walking the DOM tree and matching DOM elements to
- * {@link ng.$compileProvider#directive directives}.
- *
- * <div class="alert alert-warning">
- * **Note:** This document is an in-depth reference of all directive options.
- * For a gentle introduction to directives with examples of common use cases,
- * see the {@link guide/directive directive guide}.
- * </div>
- *
- * ## Comprehensive Directive API
- *
- * There are many different options for a directive.
- *
- * The difference resides in the return value of the factory function.
- * You can either return a {@link $compile#directive-definition-object Directive Definition Object (see below)}
- * that defines the directive properties, or just the `postLink` function (all other properties will have
- * the default values).
- *
- * <div class="alert alert-success">
- * **Best Practice:** It's recommended to use the "directive definition object" form.
- * </div>
- *
- * Here's an example directive declared with a Directive Definition Object:
- *
- * ```js
- *   var myModule = angular.module(...);
- *
- *   myModule.directive('directiveName', function factory(injectables) {
- *     var directiveDefinitionObject = {
- *       priority: 0,
- *       template: '<div></div>', // or // function(tElement, tAttrs) { ... },
- *       // or
- *       // templateUrl: 'directive.html', // or // function(tElement, tAttrs) { ... },
- *       transclude: false,
- *       restrict: 'A',
- *       templateNamespace: 'html',
- *       scope: false,
- *       controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
- *       controllerAs: 'stringIdentifier',
- *       bindToController: false,
- *       require: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],
- *       compile: function compile(tElement, tAttrs, transclude) {
- *         return {
- *           pre: function preLink(scope, iElement, iAttrs, controller) { ... },
- *           post: function postLink(scope, iElement, iAttrs, controller) { ... }
- *         }
- *         // or
- *         // return function postLink( ... ) { ... }
- *       },
- *       // or
- *       // link: {
- *       //  pre: function preLink(scope, iElement, iAttrs, controller) { ... },
- *       //  post: function postLink(scope, iElement, iAttrs, controller) { ... }
- *       // }
- *       // or
- *       // link: function postLink( ... ) { ... }
- *     };
- *     return directiveDefinitionObject;
- *   });
- * ```
- *
- * <div class="alert alert-warning">
- * **Note:** Any unspecified options will use the default value. You can see the default values below.
- * </div>
- *
- * Therefore the above can be simplified as:
- *
- * ```js
- *   var myModule = angular.module(...);
- *
- *   myModule.directive('directiveName', function factory(injectables) {
- *     var directiveDefinitionObject = {
- *       link: function postLink(scope, iElement, iAttrs) { ... }
- *     };
- *     return directiveDefinitionObject;
- *     // or
- *     // return function postLink(scope, iElement, iAttrs) { ... }
- *   });
- * ```
- *
- * ### Life-cycle hooks
- * Directive controllers can provide the following methods that are called by Angular at points in the life-cycle of the
- * directive:
- * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and
- *   had their bindings initialized (and before the pre &amp; post linking functions for the directives on
- *   this element). This is a good place to put initialization code for your controller.
- * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The
- *   `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an
- *   object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a
- *   component such as cloning the bound value to prevent accidental mutation of the outer value.
- * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on
- *   changes. Any actions that you wish to take in response to the changes that you detect must be
- *   invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook
- *   could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not
- *   be detected by Angular's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments;
- *   if detecting changes, you must store the previous value(s) for comparison to the current values.
- * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing
- *   external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in
- *   the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent
- *   components will have their `$onDestroy()` hook called before child components.
- * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link
- *   function this hook can be used to set up DOM event handlers and do direct DOM manipulation.
- *   Note that child elements that contain `templateUrl` directives will not have been compiled and linked since
- *   they are waiting for their template to load asynchronously and their own compilation and linking has been
- *   suspended until that occurs.
- *
- * #### Comparison with Angular 2 life-cycle hooks
- * Angular 2 also uses life-cycle hooks for its components. While the Angular 1 life-cycle hooks are similar there are
- * some differences that you should be aware of, especially when it comes to moving your code from Angular 1 to Angular 2:
- *
- * * Angular 1 hooks are prefixed with `$`, such as `$onInit`. Angular 2 hooks are prefixed with `ng`, such as `ngOnInit`.
- * * Angular 1 hooks can be defined on the controller prototype or added to the controller inside its constructor.
- *   In Angular 2 you can only define hooks on the prototype of the Component class.
- * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in Angular 1 than you would to
- *   `ngDoCheck` in Angular 2
- * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be
- *   propagated throughout the application.
- *   Angular 2 does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an
- *   error or do nothing depending upon the state of `enableProdMode()`.
- *
- * #### Life-cycle hook examples
- *
- * This example shows how you can check for mutations to a Date object even though the identity of the object
- * has not changed.
- *
- * <example name="doCheckDateExample" module="do-check-module">
- *   <file name="app.js">
- *     angular.module('do-check-module', [])
- *       .component('app', {
- *         template:
- *           'Month: <input ng-model="$ctrl.month" ng-change="$ctrl.updateDate()">' +
- *           'Date: {{ $ctrl.date }}' +
- *           '<test date="$ctrl.date"></test>',
- *         controller: function() {
- *           this.date = new Date();
- *           this.month = this.date.getMonth();
- *           this.updateDate = function() {
- *             this.date.setMonth(this.month);
- *           };
- *         }
- *       })
- *       .component('test', {
- *         bindings: { date: '<' },
- *         template:
- *           '<pre>{{ $ctrl.log | json }}</pre>',
- *         controller: function() {
- *           var previousValue;
- *           this.log = [];
- *           this.$doCheck = function() {
- *             var currentValue = this.date && this.date.valueOf();
- *             if (previousValue !== currentValue) {
- *               this.log.push('doCheck: date mutated: ' + this.date);
- *               previousValue = currentValue;
- *             }
- *           };
- *         }
- *       });
- *   </file>
- *   <file name="index.html">
- *     <app></app>
- *   </file>
- * </example>
- *
- * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the
- * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large
- * arrays or objects can have a negative impact on your application performance)
- *
- * <example name="doCheckArrayExample" module="do-check-module">
- *   <file name="index.html">
- *     <div ng-init="items = []">
- *       <button ng-click="items.push(items.length)">Add Item</button>
- *       <button ng-click="items = []">Reset Items</button>
- *       <pre>{{ items }}</pre>
- *       <test items="items"></test>
- *     </div>
- *   </file>
- *   <file name="app.js">
- *      angular.module('do-check-module', [])
- *        .component('test', {
- *          bindings: { items: '<' },
- *          template:
- *            '<pre>{{ $ctrl.log | json }}</pre>',
- *          controller: function() {
- *            this.log = [];
- *
- *            this.$doCheck = function() {
- *              if (this.items_ref !== this.items) {
- *                this.log.push('doCheck: items changed');
- *                this.items_ref = this.items;
- *              }
- *              if (!angular.equals(this.items_clone, this.items)) {
- *                this.log.push('doCheck: items mutated');
- *                this.items_clone = angular.copy(this.items);
- *              }
- *            };
- *          }
- *        });
- *   </file>
- * </example>

- * ### Directive Definition Object
- *
- * The directive definition object provides instructions to the {@link ng.$compile
- * compiler}. The attributes are:
- *
- * #### `multiElement`
- * When this property is set to true, the HTML compiler will collect DOM nodes between
- * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them
- * together as the directive elements. It is recommended that this feature be used on directives
- * which are not strictly behavioral (such as {@link ngClick}), and which
- * do not manipulate or replace child nodes (such as {@link ngInclude}).
- *
- * #### `priority`
- * When there are multiple directives defined on a single DOM element, sometimes it
- * is necessary to specify the order in which the directives are applied. The `priority` is used
- * to sort the directives before their `compile` functions get called. Priority is defined as a
- * number. Directives with greater numerical `priority` are compiled first. Pre-link functions
- * are also run in priority order, but post-link functions are run in reverse order. The order
- * of directives with the same priority is undefined. The default priority is `0`.
- *
- * #### `terminal`
- * If set to true then the current `priority` will be the last set of directives
- * which will execute (any directives at the current priority will still execute
- * as the order of execution on same `priority` is undefined). Note that expressions
- * and other directives used in the directive's template will also be excluded from execution.
- *
- * #### `scope`
- * The scope property can be `true`, an object or a falsy value:
- *
- * * **falsy:** No scope will be created for the directive. The directive will use its parent's scope.
- *
- * * **`true`:** A new child scope that prototypically inherits from its parent will be created for
- * the directive's element. If multiple directives on the same element request a new scope,
- * only one new scope is created. The new scope rule does not apply for the root of the template
- * since the root of the template always gets a new scope.
- *
- * * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's element. The
- * 'isolate' scope differs from normal scope in that it does not prototypically inherit from its parent
- * scope. This is useful when creating reusable components, which should not accidentally read or modify
- * data in the parent scope.
- *
- * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the
- * directive's element. These local properties are useful for aliasing values for templates. The keys in
- * the object hash map to the name of the property on the isolate scope; the values define how the property
- * is bound to the parent scope, via matching attributes on the directive's element:
- *
- * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
- *   always a string since DOM attributes are strings. If no `attr` name is specified then the
- *   attribute name is assumed to be the same as the local name. Given `<my-component
- *   my-attr="hello {{name}}">` and the isolate scope definition `scope: { localName:'@myAttr' }`,
- *   the directive's scope property `localName` will reflect the interpolated value of `hello
- *   {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's
- *   scope. The `name` is read from the parent scope (not the directive's scope).
- *
- * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression
- *   passed via the attribute `attr`. The expression is evaluated in the context of the parent scope.
- *   If no `attr` name is specified then the attribute name is assumed to be the same as the local
- *   name. Given `<my-component my-attr="parentModel">` and the isolate scope definition `scope: {
- *   localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the
- *   value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in
- *   `localModel` and vice versa. Optional attributes should be marked as such with a question mark:
- *   `=?` or `=?attr`. If the binding expression is non-assignable, or if the attribute isn't
- *   optional and doesn't exist, an exception ({@link error/$compile/nonassign `$compile:nonassign`})
- *   will be thrown upon discovering changes to the local value, since it will be impossible to sync
- *   them back to the parent scope. By default, the {@link ng.$rootScope.Scope#$watch `$watch`}
- *   method is used for tracking changes, and the equality check is based on object identity.
- *   However, if an object literal or an array literal is passed as the binding expression, the
- *   equality check is done by value (using the {@link angular.equals} function). It's also possible
- *   to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection
- *   `$watchCollection`}: use `=*` or `=*attr` (`=*?` or `=*?attr` if the attribute is optional).
- *
-  * * `<` or `<attr` - set up a one-way (one-directional) binding between a local scope property and an
- *   expression passed via the attribute `attr`. The expression is evaluated in the context of the
- *   parent scope. If no `attr` name is specified then the attribute name is assumed to be the same as the
- *   local name. You can also make the binding optional by adding `?`: `<?` or `<?attr`.
- *
- *   For example, given `<my-component my-attr="parentModel">` and directive definition of
- *   `scope: { localModel:'<myAttr' }`, then the isolated scope property `localModel` will reflect the
- *   value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected
- *   in `localModel`, but changes in `localModel` will not reflect in `parentModel`. There are however
- *   two caveats:
- *     1. one-way binding does not copy the value from the parent to the isolate scope, it simply
- *     sets the same value. That means if your bound value is an object, changes to its properties
- *     in the isolated scope will be reflected in the parent scope (because both reference the same object).
- *     2. one-way binding watches changes to the **identity** of the parent value. That means the
- *     {@link ng.$rootScope.Scope#$watch `$watch`} on the parent value only fires if the reference
- *     to the value has changed. In most cases, this should not be of concern, but can be important
- *     to know if you one-way bind to an object, and then replace that object in the isolated scope.
- *     If you now change a property of the object in your parent scope, the change will not be
- *     propagated to the isolated scope, because the identity of the object on the parent scope
- *     has not changed. Instead you must assign a new object.
- *
- *   One-way binding is useful if you do not plan to propagate changes to your isolated scope bindings
- *   back to the parent. However, it does not make this completely impossible.
- *
- * * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope. If
- *   no `attr` name is specified then the attribute name is assumed to be the same as the local name.
- *   Given `<my-component my-attr="count = count + value">` and the isolate scope definition `scope: {
- *   localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for
- *   the `count = count + value` expression. Often it's desirable to pass data from the isolated scope
- *   via an expression to the parent scope. This can be done by passing a map of local variable names
- *   and values into the expression wrapper fn. For example, if the expression is `increment(amount)`
- *   then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`.
- *
- * In general it's possible to apply more than one directive to one element, but there might be limitations
- * depending on the type of scope required by the directives. The following points will help explain these limitations.
- * For simplicity only two directives are taken into account, but it is also applicable for several directives:
- *
- * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope
- * * **child scope** + **no scope** =>  Both directives will share one single child scope
- * * **child scope** + **child scope** =>  Both directives will share one single child scope
- * * **isolated scope** + **no scope** =>  The isolated directive will use it's own created isolated scope. The other directive will use
- * its parent's scope
- * * **isolated scope** + **child scope** =>  **Won't work!** Only one scope can be related to one element. Therefore these directives cannot
- * be applied to the same element.
- * * **isolated scope** + **isolated scope**  =>  **Won't work!** Only one scope can be related to one element. Therefore these directives
- * cannot be applied to the same element.
- *
- *
- * #### `bindToController`
- * This property is used to bind scope properties directly to the controller. It can be either
- * `true` or an object hash with the same format as the `scope` property. Additionally, a controller
- * alias must be set, either by using `controllerAs: 'myAlias'` or by specifying the alias in the controller
- * definition: `controller: 'myCtrl as myAlias'`.
- *
- * When an isolate scope is used for a directive (see above), `bindToController: true` will
- * allow a component to have its properties bound to the controller, rather than to scope.
- *
- * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller
- * properties. You can access these bindings once they have been initialized by providing a controller method called
- * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings
- * initialized.
- *
- * <div class="alert alert-warning">
- * **Deprecation warning:** although bindings for non-ES6 class controllers are currently
- * bound to `this` before the controller constructor is called, this use is now deprecated. Please place initialization
- * code that relies upon bindings inside a `$onInit` method on the controller, instead.
- * </div>
- *
- * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property.
- * This will set up the scope bindings to the controller directly. Note that `scope` can still be used
- * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate
- * scope (useful for component directives).
- *
- * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`.
- *
- *
- * #### `controller`
- * Controller constructor function. The controller is instantiated before the
- * pre-linking phase and can be accessed by other directives (see
- * `require` attribute). This allows the directives to communicate with each other and augment
- * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
- *
- * * `$scope` - Current scope associated with the element
- * * `$element` - Current element
- * * `$attrs` - Current attributes object for the element
- * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:
- *   `function([scope], cloneLinkingFn, futureParentElement, slotName)`:
- *    * `scope`: (optional) override the scope.
- *    * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content.
- *    * `futureParentElement` (optional):
- *        * defines the parent to which the `cloneLinkingFn` will add the cloned elements.
- *        * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.
- *        * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)
- *          and when the `cloneLinkinFn` is passed,
- *          as those elements need to created and cloned in a special way when they are defined outside their
- *          usual containers (e.g. like `<svg>`).
- *        * See also the `directive.templateNamespace` property.
- *    * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`)
- *      then the default translusion is provided.
- *    The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns
- *    `true` if the specified slot contains content (i.e. one or more DOM nodes).
- *
- * #### `require`
- * Require another directive and inject its controller as the fourth argument to the linking function. The
- * `require` property can be a string, an array or an object:
- * * a **string** containing the name of the directive to pass to the linking function
- * * an **array** containing the names of directives to pass to the linking function. The argument passed to the
- * linking function will be an array of controllers in the same order as the names in the `require` property
- * * an **object** whose property values are the names of the directives to pass to the linking function. The argument
- * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding
- * controllers.
- *
- * If the `require` property is an object and `bindToController` is truthy, then the required controllers are
- * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers
- * have been constructed but before `$onInit` is called.
- * If the name of the required controller is the same as the local name (the key), the name can be
- * omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`.
- * See the {@link $compileProvider#component} helper for an example of how this can be used.
- * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is
- * raised (unless no link function is specified and the required controllers are not being bound to the directive
- * controller, in which case error checking is skipped). The name can be prefixed with:
- *
- * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
- * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
- * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.
- * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.
- * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass
- *   `null` to the `link` fn if not found.
- * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass
- *   `null` to the `link` fn if not found.
- *
- *
- * #### `controllerAs`
- * Identifier name for a reference to the controller in the directive's scope.
- * This allows the controller to be referenced from the directive template. This is especially
- * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible
- * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the
- * `controllerAs` reference might overwrite a property that already exists on the parent scope.
- *
- *
- * #### `restrict`
- * String of subset of `EACM` which restricts the directive to a specific directive
- * declaration style. If omitted, the defaults (elements and attributes) are used.
- *
- * * `E` - Element name (default): `<my-directive></my-directive>`
- * * `A` - Attribute (default): `<div my-directive="exp"></div>`
- * * `C` - Class: `<div class="my-directive: exp;"></div>`
- * * `M` - Comment: `<!-- directive: my-directive exp -->`
- *
- *
- * #### `templateNamespace`
- * String representing the document type used by the markup in the template.
- * AngularJS needs this information as those elements need to be created and cloned
- * in a special way when they are defined outside their usual containers like `<svg>` and `<math>`.
- *
- * * `html` - All root nodes in the template are HTML. Root nodes may also be
- *   top-level elements such as `<svg>` or `<math>`.
- * * `svg` - The root nodes in the template are SVG elements (excluding `<math>`).
- * * `math` - The root nodes in the template are MathML elements (excluding `<svg>`).
- *
- * If no `templateNamespace` is specified, then the namespace is considered to be `html`.
- *
- * #### `template`
- * HTML markup that may:
- * * Replace the contents of the directive's element (default).
- * * Replace the directive's element itself (if `replace` is true - DEPRECATED).
- * * Wrap the contents of the directive's element (if `transclude` is true).
- *
- * Value may be:
- *
- * * A string. For example `<div red-on-hover>{{delete_str}}</div>`.
- * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`
- *   function api below) and returns a string value.
- *
- *
- * #### `templateUrl`
- * This is similar to `template` but the template is loaded from the specified URL, asynchronously.
- *
- * Because template loading is asynchronous the compiler will suspend compilation of directives on that element
- * for later when the template has been resolved.  In the meantime it will continue to compile and link
- * sibling and parent elements as though this element had not contained any directives.
- *
- * The compiler does not suspend the entire compilation to wait for templates to be loaded because this
- * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the
- * case when only one deeply nested directive has `templateUrl`.
- *
- * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}
- *
- * You can specify `templateUrl` as a string representing the URL or as a function which takes two
- * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
- * a string value representing the url.  In either case, the template URL is passed through {@link
- * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.
- *
- *
- * #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0)
- * specify what the template should replace. Defaults to `false`.
- *
- * * `true` - the template will replace the directive's element.
- * * `false` - the template will replace the contents of the directive's element.
- *
- * The replacement process migrates all of the attributes / classes from the old element to the new
- * one. See the {@link guide/directive#template-expanding-directive
- * Directives Guide} for an example.
- *
- * There are very few scenarios where element replacement is required for the application function,
- * the main one being reusable custom components that are used within SVG contexts
- * (because SVG doesn't work with custom elements in the DOM tree).
- *
- * #### `transclude`
- * Extract the contents of the element where the directive appears and make it available to the directive.
- * The contents are compiled and provided to the directive as a **transclusion function**. See the
- * {@link $compile#transclusion Transclusion} section below.
- *
- *
- * #### `compile`
- *
- * ```js
- *   function compile(tElement, tAttrs, transclude) { ... }
- * ```
- *
- * The compile function deals with transforming the template DOM. Since most directives do not do
- * template transformation, it is not used often. The compile function takes the following arguments:
- *
- *   * `tElement` - template element - The element where the directive has been declared. It is
- *     safe to do template transformation on the element and child elements only.
- *
- *   * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
- *     between all directive compile functions.
- *
- *   * `transclude` -  [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`
- *
- * <div class="alert alert-warning">
- * **Note:** The template instance and the link instance may be different objects if the template has
- * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
- * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
- * should be done in a linking function rather than in a compile function.
- * </div>
-
- * <div class="alert alert-warning">
- * **Note:** The compile function cannot handle directives that recursively use themselves in their
- * own templates or compile functions. Compiling these directives results in an infinite loop and
- * stack overflow errors.
- *
- * This can be avoided by manually using $compile in the postLink function to imperatively compile
- * a directive's template instead of relying on automatic template compilation via `template` or
- * `templateUrl` declaration or manual compilation inside the compile function.
- * </div>
- *
- * <div class="alert alert-danger">
- * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it
- *   e.g. does not know about the right outer scope. Please use the transclude function that is passed
- *   to the link function instead.
- * </div>
-
- * A compile function can have a return value which can be either a function or an object.
- *
- * * returning a (post-link) function - is equivalent to registering the linking function via the
- *   `link` property of the config object when the compile function is empty.
- *
- * * returning an object with function(s) registered via `pre` and `post` properties - allows you to
- *   control when a linking function should be called during the linking phase. See info about
- *   pre-linking and post-linking functions below.
- *
- *
- * #### `link`
- * This property is used only if the `compile` property is not defined.
- *
- * ```js
- *   function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
- * ```
- *
- * The link function is responsible for registering DOM listeners as well as updating the DOM. It is
- * executed after the template has been cloned. This is where most of the directive logic will be
- * put.
- *
- *   * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the
- *     directive for registering {@link ng.$rootScope.Scope#$watch watches}.
- *
- *   * `iElement` - instance element - The element where the directive is to be used. It is safe to
- *     manipulate the children of the element only in `postLink` function since the children have
- *     already been linked.
- *
- *   * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
- *     between all directive linking functions.
- *
- *   * `controller` - the directive's required controller instance(s) - Instances are shared
- *     among all directives, which allows the directives to use the controllers as a communication
- *     channel. The exact value depends on the directive's `require` property:
- *       * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one
- *       * `string`: the controller instance
- *       * `array`: array of controller instances
- *
- *     If a required controller cannot be found, and it is optional, the instance is `null`,
- *     otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.
- *
- *     Note that you can also require the directive's own controller - it will be made available like
- *     any other controller.
- *
- *   * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
- *     This is the same as the `$transclude` parameter of directive controllers,
- *     see {@link ng.$compile#-controller- the controller section for details}.
- *     `function([scope], cloneLinkingFn, futureParentElement)`.
- *
- * #### Pre-linking function
- *
- * Executed before the child elements are linked. Not safe to do DOM transformation since the
- * compiler linking function will fail to locate the correct elements for linking.
- *
- * #### Post-linking function
- *
- * Executed after the child elements are linked.
- *
- * Note that child elements that contain `templateUrl` directives will not have been compiled
- * and linked since they are waiting for their template to load asynchronously and their own
- * compilation and linking has been suspended until that occurs.
- *
- * It is safe to do DOM transformation in the post-linking function on elements that are not waiting
- * for their async templates to be resolved.
- *
- *
- * ### Transclusion
- *
- * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and
- * copying them to another part of the DOM, while maintaining their connection to the original AngularJS
- * scope from where they were taken.
- *
- * Transclusion is used (often with {@link ngTransclude}) to insert the
- * original contents of a directive's element into a specified place in the template of the directive.
- * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded
- * content has access to the properties on the scope from which it was taken, even if the directive
- * has isolated scope.
- * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.
- *
- * This makes it possible for the widget to have private state for its template, while the transcluded
- * content has access to its originating scope.
- *
- * <div class="alert alert-warning">
- * **Note:** When testing an element transclude directive you must not place the directive at the root of the
- * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives
- * Testing Transclusion Directives}.
- * </div>
- *
- * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the
- * directive's element, the entire element or multiple parts of the element contents:
- *
- * * `true` - transclude the content (i.e. the child nodes) of the directive's element.
- * * `'element'` - transclude the whole of the directive's element including any directives on this
- *   element that defined at a lower priority than this directive. When used, the `template`
- *   property is ignored.
- * * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template.
- *
- * **Mult-slot transclusion** is declared by providing an object for the `transclude` property.
- *
- * This object is a map where the keys are the name of the slot to fill and the value is an element selector
- * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`)
- * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc).
- *
- * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives}
- *
- * If the element selector is prefixed with a `?` then that slot is optional.
- *
- * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `<my-custom-element>` elements to
- * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive.
- *
- * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements
- * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call
- * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and
- * injectable into the directive's controller.
- *
- *
- * #### Transclusion Functions
- *
- * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion
- * function** to the directive's `link` function and `controller`. This transclusion function is a special
- * **linking function** that will return the compiled contents linked to a new transclusion scope.
- *
- * <div class="alert alert-info">
- * If you are just using {@link ngTransclude} then you don't need to worry about this function, since
- * ngTransclude will deal with it for us.
- * </div>
- *
- * If you want to manually control the insertion and removal of the transcluded content in your directive
- * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery
- * object that contains the compiled DOM, which is linked to the correct transclusion scope.
- *
- * When you call a transclusion function you can pass in a **clone attach function**. This function accepts
- * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded
- * content and the `scope` is the newly created transclusion scope, to which the clone is bound.
- *
- * <div class="alert alert-info">
- * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function
- * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.
- * </div>
- *
- * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone
- * attach function**:
- *
- * ```js
- * var transcludedContent, transclusionScope;
- *
- * $transclude(function(clone, scope) {
- *   element.append(clone);
- *   transcludedContent = clone;
- *   transclusionScope = scope;
- * });
- * ```
- *
- * Later, if you want to remove the transcluded content from your DOM then you should also destroy the
- * associated transclusion scope:
- *
- * ```js
- * transcludedContent.remove();
- * transclusionScope.$destroy();
- * ```
- *
- * <div class="alert alert-info">
- * **Best Practice**: if you intend to add and remove transcluded content manually in your directive
- * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),
- * then you are also responsible for calling `$destroy` on the transclusion scope.
- * </div>
- *
- * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}
- * automatically destroy their transcluded clones as necessary so you do not need to worry about this if
- * you are simply using {@link ngTransclude} to inject the transclusion into your directive.
- *
- *
- * #### Transclusion Scopes
- *
- * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion
- * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed
- * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it
- * was taken.
- *
- * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look
- * like this:
- *
- * ```html
- * <div ng-app>
- *   <div isolate>
- *     <div transclusion>
- *     </div>
- *   </div>
- * </div>
- * ```
- *
- * The `$parent` scope hierarchy will look like this:
- *
-   ```
-   - $rootScope
-     - isolate
-       - transclusion
-   ```
- *
- * but the scopes will inherit prototypically from different scopes to their `$parent`.
- *
-   ```
-   - $rootScope
-     - transclusion
-   - isolate
-   ```
- *
- *
- * ### Attributes
- *
- * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
- * `link()` or `compile()` functions. It has a variety of uses.
- *
- * * *Accessing normalized attribute names:* Directives like 'ngBind' can be expressed in many ways:
- *   'ng:bind', `data-ng-bind`, or 'x-ng-bind'. The attributes object allows for normalized access
- *   to the attributes.
- *
- * * *Directive inter-communication:* All directives share the same instance of the attributes
- *   object which allows the directives to use the attributes object as inter directive
- *   communication.
- *
- * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
- *   allowing other directives to read the interpolated value.
- *
- * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
- *   that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
- *   the only way to easily get the actual value because during the linking phase the interpolation
- *   hasn't been evaluated yet and so the value is at this time set to `undefined`.
- *
- * ```js
- * function linkingFn(scope, elm, attrs, ctrl) {
- *   // get the attribute value
- *   console.log(attrs.ngModel);
- *
- *   // change the attribute
- *   attrs.$set('ngModel', 'new value');
- *
- *   // observe changes to interpolated attribute
- *   attrs.$observe('ngModel', function(value) {
- *     console.log('ngModel has changed value to ' + value);
- *   });
- * }
- * ```
- *
- * ## Example
- *
- * <div class="alert alert-warning">
- * **Note**: Typically directives are registered with `module.directive`. The example below is
- * to illustrate how `$compile` works.
- * </div>
- *
- <example module="compileExample">
-   <file name="index.html">
-    <script>
-      angular.module('compileExample', [], function($compileProvider) {
-        // configure new 'compile' directive by passing a directive

-        $compileProvider.directive('compile', function($compile) {
-          // directive factory creates a link function
-          return function(scope, element, attrs) {

- *          parent: {
- *            instance: parentControllerInstance
- *          }
- *        }
- *        ```
- *      * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add
- *        the cloned elements; only needed for transcludes that are allowed to contain non html
- *        elements (e.g. SVG elements). See also the directive.controller property.
- *
- * Calling the linking function returns the element of the template. It is either the original
- * element passed in, or the clone of the element if the `cloneAttachFn` is provided.
- *
- * After linking the view is not updated until after a call to $digest which typically is done by
- * Angular automatically.
- *
- * If you need access to the bound view, there are two ways to do it:
- *
- * - If you are not asking the linking function to clone the template, create the DOM element(s)
- *   before you send them to the compiler and keep this reference around.
- *   ```js
- *     var element = $compile('<p>{{total}}</p>')(scope);
- *   ```
- *
- * - if on the other hand, you need the element to be cloned, the view reference from the original
- *   example would not point to the clone, but rather to the original template that was cloned. In
- *   this case, you can access the clone via the cloneAttachFn:
- *   ```js
- *     var templateElement = angular.element('<p>{{total}}</p>'),
- *         scope = ....;
- *
- *     var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
- *       //attach the clone to DOM document at the right place
- *     });
- *
- *     //now we have reference to the cloned DOM via `clonedElement`
- *   ```
- *
- *
- * For information on how the compiler works, see the
- * {@link guide/compiler Angular HTML Compiler} section of the Developer Guide.

-   * @description
-   * Register a **component definition** with the compiler. This is a shorthand for registering a special
-   * type of directive, which represents a self-contained UI component in your application. Such components
-   * are always isolated (i.e. `scope: {}`) and are always restricted to elements (i.e. `restrict: 'E'`).
-   *
-   * Component definitions are very simple and do not require as much configuration as defining general
-   * directives. Component definitions usually consist only of a template and a controller backing it.
-   *
-   * In order to make the definition easier, components enforce best practices like use of `controllerAs`,
-   * `bindToController`. They always have **isolate scope** and are restricted to elements.
-   *
-   * Here are a few examples of how you would usually define components:
-   *
-   * ```js
-   *   var myMod = angular.module(...);
-   *   myMod.component('myComp', {
-   *     template: '<div>My name is {{$ctrl.name}}</div>',
-   *     controller: function() {
-   *       this.name = 'shahar';
-   *     }
-   *   });
-   *
-   *   myMod.component('myComp', {
-   *     template: '<div>My name is {{$ctrl.name}}</div>',
-   *     bindings: {name: '@'}
-   *   });
-   *
-   *   myMod.component('myComp', {
-   *     templateUrl: 'views/my-comp.html',
-   *     controller: 'MyCtrl',
-   *     controllerAs: 'ctrl',
-   *     bindings: {name: '@'}
-   *   });
-   *
-   * ```
-   * For more examples, and an in-depth guide, see the {@link guide/component component guide}.

-/**
- * @ngdoc service
- * @name $exceptionHandler
- * @requires ng.$log
- *
- * @description
- * Any uncaught exception in angular expressions is delegated to this service.
- * The default implementation simply delegates to `$log.error` which logs it into
- * the browser console.
- *
- * In unit tests, if `angular-mocks.js` is loaded, this service is overridden by
- * {@link ngMock.$exceptionHandler mock $exceptionHandler} which aids in testing.
- *
- * ## Example:
- *
- * The example below will overwrite the default `$exceptionHandler` in order to (a) log uncaught
- * errors to the backend for later inspection by the developers and (b) to use `$log.warn()` instead
- * of `$log.error()`.
- *
- * ```js
- *   angular.
- *     module('exceptionOverwrite', []).
- *     factory('$exceptionHandler', ['$log', 'logErrorsToBackend', function($log, logErrorsToBackend) {
- *       return function myExceptionHandler(exception, cause) {
- *         logErrorsToBackend(exception, cause);
- *         $log.warn(exception, cause);
- *       };
- *     }]);
- * ```
- *
- * <hr />
- * Note, that code executed in event-listeners (even those registered using jqLite's `on`/`bind`
- * methods) does not delegate exceptions to the {@link ng.$exceptionHandler $exceptionHandler}
- * (unless executed during a digest).
- *
- * If you wish, you can manually delegate exceptions, e.g.
- * `try { ... } catch(e) { $exceptionHandler(e); }`
- *
- * @param {Error} exception Exception associated with the error.
- * @param {string=} cause Optional information about the context in which
- *       the error was thrown.

-     * The `$http` service is a core Angular service that facilitates communication with the remote
-     * HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest)
-     * object or via [JSONP](http://en.wikipedia.org/wiki/JSONP).
-     *
-     * For unit testing applications that use `$http` service, see
-     * {@link ngMock.$httpBackend $httpBackend mock}.
-     *
-     * For a higher level of abstraction, please check out the {@link ngResource.$resource
-     * $resource} service.
-     *
-     * The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
-     * the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
-     * it is important to familiarize yourself with these APIs and the guarantees they provide.
-     *
-     *
-     * ## General usage
-     * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} —
-     * that is used to generate an HTTP request and returns  a {@link ng.$q promise}.
-     *
-     * ```js
-     *   // Simple GET request example:
-     *   $http({
-     *     method: 'GET',
-     *     url: '/someUrl'
-     *   }).then(function successCallback(response) {
-     *       // this callback will be called asynchronously
-     *       // when the response is available
-     *     }, function errorCallback(response) {
-     *       // called asynchronously if an error occurs
-     *       // or server returns response with an error status.
-     *     });
-     * ```
-     *
-     * The response object has these properties:
-     *
-     *   - **data** – `{string|Object}` – The response body transformed with the transform
-     *     functions.
-     *   - **status** – `{number}` – HTTP status code of the response.
-     *   - **headers** – `{function([headerName])}` – Header getter function.
-     *   - **config** – `{Object}` – The configuration object that was used to generate the request.
-     *   - **statusText** – `{string}` – HTTP status text of the response.
-     *
-     * A response status code between 200 and 299 is considered a success status and will result in
-     * the success callback being called. Any response status code outside of that range is
-     * considered an error status and will result in the error callback being called.
-     * Also, status codes less than -1 are normalized to zero. -1 usually means the request was
-     * aborted, e.g. using a `config.timeout`.
-     * Note that if the response is a redirect, XMLHttpRequest will transparently follow it, meaning
-     * that the outcome (success or error) will be determined by the final response status code.
-     *
-     *
-     * ## Shortcut methods
-     *
-     * Shortcut methods are also available. All shortcut methods require passing in the URL, and
-     * request data must be passed in for POST/PUT requests. An optional config can be passed as the
-     * last argument.
-     *
-     * ```js
-     *   $http.get('/someUrl', config).then(successCallback, errorCallback);
-     *   $http.post('/someUrl', data, config).then(successCallback, errorCallback);
-     * ```
-     *
-     * Complete list of shortcut methods:
-     *
-     * - {@link ng.$http#get $http.get}
-     * - {@link ng.$http#head $http.head}
-     * - {@link ng.$http#post $http.post}
-     * - {@link ng.$http#put $http.put}
-     * - {@link ng.$http#delete $http.delete}
-     * - {@link ng.$http#jsonp $http.jsonp}
-     * - {@link ng.$http#patch $http.patch}
-     *
-     *
-     * ## Writing Unit Tests that use $http
-     * When unit testing (using {@link ngMock ngMock}), it is necessary to call
-     * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending
-     * request using trained responses.
-     *
-     * ```
-     * $httpBackend.expectGET(...);
-     * $http.get(...);
-     * $httpBackend.flush();
-     * ```
-     *
-     * ## Deprecation Notice
-     * <div class="alert alert-danger">
-     *   The `$http` legacy promise methods `success` and `error` have been deprecated.
-     *   Use the standard `then` method instead.
-     *   If {@link $httpProvider#useLegacyPromiseExtensions `$httpProvider.useLegacyPromiseExtensions`} is set to
-     *   `false` then these methods will throw {@link $http:legacy `$http/legacy`} error.
-     * </div>
-     *
-     * ## Setting HTTP Headers
-     *
-     * The $http service will automatically add certain HTTP headers to all requests. These defaults
-     * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
-     * object, which currently contains this default configuration:
-     *
-     * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
-     *   - `Accept: application/json, text/plain, * / *`
-     * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
-     *   - `Content-Type: application/json`
-     * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
-     *   - `Content-Type: application/json`
-     *
-     * To add or overwrite these defaults, simply add or remove a property from these configuration
-     * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
-     * with the lowercased HTTP method name as the key, e.g.
-     * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.
-     *
-     * The defaults can also be set at runtime via the `$http.defaults` object in the same
-     * fashion. For example:
-     *
-     * ```
-     * module.run(function($http) {
-     *   $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w';
-     * });
-     * ```
-     *
-     * In addition, you can supply a `headers` property in the config object passed when
-     * calling `$http(config)`, which overrides the defaults without changing them globally.
-     *
-     * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,
-     * Use the `headers` property, setting the desired header to `undefined`. For example:
-     *
-     * ```js
-     * var req = {
-     *  method: 'POST',
-     *  url: 'http://example.com',
-     *  headers: {
-     *    'Content-Type': undefined
-     *  },
-     *  data: { test: 'test' }
-     * }
-     *
-     * $http(req).then(function(){...}, function(){...});
-     * ```
-     *
-     * ## Transforming Requests and Responses
-     *
-     * Both requests and responses can be transformed using transformation functions: `transformRequest`
-     * and `transformResponse`. These properties can be a single function that returns
-     * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,
-     * which allows you to `push` or `unshift` a new transformation function into the transformation chain.
-     *
-     * <div class="alert alert-warning">
-     * **Note:** Angular does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline.
-     * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference).
-     * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest
-     * function will be reflected on the scope and in any templates where the object is data-bound.
-     * To prevent this, transform functions should have no side-effects.
-     * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return.
-     * </div>
-     *
-     * ### Default Transformations
-     *
-     * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and
-     * `defaults.transformResponse` properties. If a request does not provide its own transformations
-     * then these will be applied.
-     *
-     * You can augment or replace the default transformations by modifying these properties by adding to or
-     * replacing the array.
-     *
-     * Angular provides the following default transformations:
-     *
-     * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`):
-     *
-     * - If the `data` property of the request configuration object contains an object, serialize it
-     *   into JSON format.
-     *
-     * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`):
-     *
-     *  - If XSRF prefix is detected, strip it (see Security Considerations section below).
-     *  - If JSON response is detected, deserialize it using a JSON parser.
-     *
-     *
-     * ### Overriding the Default Transformations Per Request
-     *
-     * If you wish to override the request/response transformations only for a single request then provide
-     * `transformRequest` and/or `transformResponse` properties on the configuration object passed
-     * into `$http`.
-     *
-     * Note that if you provide these properties on the config object the default transformations will be
-     * overwritten. If you wish to augment the default transformations then you must include them in your
-     * local transformation array.
-     *
-     * The following code demonstrates adding a new response transformation to be run after the default response
-     * transformations have been run.
-     *
-     * ```js
-     * function appendTransform(defaults, transform) {
-     *
-     *   // We can't guarantee that the default transformation is an array
-     *   defaults = angular.isArray(defaults) ? defaults : [defaults];
-     *
-     *   // Append the new transformation to the defaults
-     *   return defaults.concat(transform);
-     * }
-     *
-     * $http({
-     *   url: '...',
-     *   method: 'GET',
-     *   transformResponse: appendTransform($http.defaults.transformResponse, function(value) {
-     *     return doTransform(value);
-     *   })
-     * });
-     * ```
-     *
-     *
-     * ## Caching
-     *
-     * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must
-     * set the config.cache value or the default cache value to TRUE or to a cache object (created
-     * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes
-     * precedence over the default cache value.
-     *
-     * In order to:
-     *   * cache all responses - set the default cache value to TRUE or to a cache object
-     *   * cache a specific response - set config.cache value to TRUE or to a cache object
-     *
-     * If caching is enabled, but neither the default cache nor config.cache are set to a cache object,
-     * then the default `$cacheFactory("$http")` object is used.
-     *
-     * The default cache value can be set by updating the
-     * {@link ng.$http#defaults `$http.defaults.cache`} property or the
-     * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property.
-     *
-     * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using
-     * the relevant cache object. The next time the same request is made, the response is returned
-     * from the cache without sending a request to the server.
-     *
-     * Take note that:
-     *
-     *   * Only GET and JSONP requests are cached.
-     *   * The cache key is the request URL including search parameters; headers are not considered.
-     *   * Cached responses are returned asynchronously, in the same way as responses from the server.
-     *   * If multiple identical requests are made using the same cache, which is not yet populated,
-     *     one request will be made to the server and remaining requests will return the same response.
-     *   * A cache-control header on the response does not affect if or how responses are cached.
-     *
-     *
-     * ## Interceptors
-     *
-     * Before you start creating interceptors, be sure to understand the
-     * {@link ng.$q $q and deferred/promise APIs}.
-     *
-     * For purposes of global error handling, authentication, or any kind of synchronous or
-     * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
-     * able to intercept requests before they are handed to the server and
-     * responses before they are handed over to the application code that
-     * initiated these requests. The interceptors leverage the {@link ng.$q
-     * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
-     *
-     * The interceptors are service factories that are registered with the `$httpProvider` by
-     * adding them to the `$httpProvider.interceptors` array. The factory is called and
-     * injected with dependencies (if specified) and returns the interceptor.
-     *
-     * There are two kinds of interceptors (and two kinds of rejection interceptors):
-     *
-     *   * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to
-     *     modify the `config` object or create a new one. The function needs to return the `config`
-     *     object directly, or a promise containing the `config` or a new `config` object.
-     *   * `requestError`: interceptor gets called when a previous interceptor threw an error or
-     *     resolved with a rejection.
-     *   * `response`: interceptors get called with http `response` object. The function is free to
-     *     modify the `response` object or create a new one. The function needs to return the `response`
-     *     object directly, or as a promise containing the `response` or a new `response` object.
-     *   * `responseError`: interceptor gets called when a previous interceptor threw an error or
-     *     resolved with a rejection.
-     *
-     *
-     * ```js
-     *   // register the interceptor as a service
-     *   $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
-     *     return {
-     *       // optional method
-     *       'request': function(config) {
-     *         // do something on success
-     *         return config;
-     *       },
-     *
-     *       // optional method
-     *      'requestError': function(rejection) {
-     *         // do something on error
-     *         if (canRecover(rejection)) {
-     *           return responseOrNewPromise
-     *         }
-     *         return $q.reject(rejection);
-     *       },
-     *
-     *
-     *
-     *       // optional method
-     *       'response': function(response) {
-     *         // do something on success
-     *         return response;
-     *       },
-     *
-     *       // optional method
-     *      'responseError': function(rejection) {
-     *         // do something on error
-     *         if (canRecover(rejection)) {
-     *           return responseOrNewPromise
-     *         }
-     *         return $q.reject(rejection);
-     *       }
-     *     };
-     *   });
-     *
-     *   $httpProvider.interceptors.push('myHttpInterceptor');
-     *
-     *
-     *   // alternatively, register the interceptor via an anonymous factory
-     *   $httpProvider.interceptors.push(function($q, dependency1, dependency2) {
-     *     return {
-     *      'request': function(config) {
-     *          // same as above
-     *       },
-     *
-     *       'response': function(response) {
-     *          // same as above
-     *       }
-     *     };
-     *   });
-     * ```
-     *
-     * ## Security Considerations
-     *
-     * When designing web applications, consider security threats from:
-     *
-     * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
-     * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
-     *
-     * Both server and the client must cooperate in order to eliminate these threats. Angular comes
-     * pre-configured with strategies that address these issues, but for this to work backend server
-     * cooperation is required.
-     *
-     * ### JSON Vulnerability Protection
-     *
-     * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
-     * allows third party website to turn your JSON resource URL into
-     * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To
-     * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
-     * Angular will automatically strip the prefix before processing it as JSON.
-     *
-     * For example if your server needs to return:
-     * ```js
-     * ['one','two']
-     * ```
-     *
-     * which is vulnerable to attack, your server can return:
-     * ```js
-     * )]}',
-     * ['one','two']
-     * ```
-     *
-     * Angular will strip the prefix, before processing the JSON.
-     *
-     *
-     * ### Cross Site Request Forgery (XSRF) Protection
-     *
-     * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by
-     * which the attacker can trick an authenticated user into unknowingly executing actions on your
-     * website. Angular provides a mechanism to counter XSRF. When performing XHR requests, the
-     * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP
-     * header (`X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read the
-     * cookie, your server can be assured that the XHR came from JavaScript running on your domain.
-     * The header will not be set for cross-domain requests.
-     *
-     * To take advantage of this, your server needs to set a token in a JavaScript readable session
-     * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
-     * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
-     * that only JavaScript running on your domain could have sent the request. The token must be
-     * unique for each user and must be verifiable by the server (to prevent the JavaScript from
-     * making up its own tokens). We recommend that the token is a digest of your site's
-     * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography&#41;)
-     * for added security.
-     *
-     * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName
-     * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,
-     * or the per-request config object.
-     *
-     * In order to prevent collisions in environments where multiple Angular apps share the
-     * same domain or subdomain, we recommend that each application uses unique cookie name.
-     *
-     * @param {object} config Object describing the request to be made and how it should be
-     *    processed. The object has following properties:
-     *
-     *    - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
-     *    - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.
-     *    - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be serialized
-     *      with the `paramSerializer` and appended as GET parameters.
-     *    - **data** – `{string|Object}` – Data to be sent as the request message data.
-     *    - **headers** – `{Object}` – Map of strings or functions which return strings representing
-     *      HTTP headers to send to the server. If the return value of a function is null, the
-     *      header will not be sent. Functions accept a config object as an argument.
-     *    - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object.
-     *      To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`.
-     *      The handler will be called in the context of a `$apply` block.
-     *    - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload
-     *      object. To bind events to the XMLHttpRequest object, use `eventHandlers`.
-     *      The handler will be called in the context of a `$apply` block.
-     *    - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
-     *    - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
-     *    - **transformRequest** –
-     *      `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
-     *      transform function or an array of such functions. The transform function takes the http
-     *      request body and headers and returns its transformed (typically serialized) version.
-     *      See {@link ng.$http#overriding-the-default-transformations-per-request
-     *      Overriding the Default Transformations}
-     *    - **transformResponse** –
-     *      `{function(data, headersGetter, status)|Array.<function(data, headersGetter, status)>}` –
-     *      transform function or an array of such functions. The transform function takes the http
-     *      response body, headers and status and returns its transformed (typically deserialized) version.
-     *      See {@link ng.$http#overriding-the-default-transformations-per-request
-     *      Overriding the Default Transformations}
-     *    - **paramSerializer** - `{string|function(Object<string,string>):string}` - A function used to
-     *      prepare the string representation of request parameters (specified as an object).
-     *      If specified as string, it is interpreted as function registered with the
-     *      {@link $injector $injector}, which means you can create your own serializer
-     *      by registering it as a {@link auto.$provide#service service}.
-     *      The default serializer is the {@link $httpParamSerializer $httpParamSerializer};
-     *      alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike}
-     *    - **cache** – `{boolean|Object}` – A boolean value or object created with
-     *      {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response.
-     *      See {@link $http#caching $http Caching} for more information.
-     *    - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
-     *      that should abort the request when resolved.
-     *    - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the
-     *      XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
-     *      for more information.
-     *    - **responseType** - `{string}` - see
-     *      [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype).
-     *
-     * @returns {HttpPromise} Returns a {@link ng.$q `Promise}` that will be resolved to a response object
-     *                        when the request succeeds or fails.
-     *
-     *
-     * @property {Array.<Object>} pendingRequests Array of config objects for currently pending
-     *   requests. This is primarily meant to be used for debugging purposes.
-     *

-     *
-     * @description
-     *
-     * Compiles a string with markup into an interpolation function. This service is used by the
-     * HTML {@link ng.$compile $compile} service for data binding. See
-     * {@link ng.$interpolateProvider $interpolateProvider} for configuring the
-     * interpolation markup.
-     *
-     *
-     * ```js
-     *   var $interpolate = ...; // injected
-     *   var exp = $interpolate('Hello {{name | uppercase}}!');
-     *   expect(exp({name:'Angular'})).toEqual('Hello ANGULAR!');
-     * ```
-     *
-     * `$interpolate` takes an optional fourth argument, `allOrNothing`. If `allOrNothing` is
-     * `true`, the interpolation function will return `undefined` unless all embedded expressions
-     * evaluate to a value other than `undefined`.
-     *
-     * ```js
-     *   var $interpolate = ...; // injected
-     *   var context = {greeting: 'Hello', name: undefined };
-     *
-     *   // default "forgiving" mode
-     *   var exp = $interpolate('{{greeting}} {{name}}!');
-     *   expect(exp(context)).toEqual('Hello !');
-     *
-     *   // "allOrNothing" mode
-     *   exp = $interpolate('{{greeting}} {{name}}!', false, null, true);
-     *   expect(exp(context)).toBeUndefined();
-     *   context.name = 'Angular';
-     *   expect(exp(context)).toEqual('Hello Angular!');
-     * ```
-     *
-     * `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior.
-     *
-     * #### Escaped Interpolation
-     * $interpolate provides a mechanism for escaping interpolation markers. Start and end markers
-     * can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).
-     * It will be rendered as a regular start/end marker, and will not be interpreted as an expression
-     * or binding.
-     *
-     * This enables web-servers to prevent script injection attacks and defacing attacks, to some
-     * degree, while also enabling code examples to work without relying on the
-     * {@link ng.directive:ngNonBindable ngNonBindable} directive.
-     *
-     * **For security purposes, it is strongly encouraged that web servers escape user-supplied data,
-     * replacing angle brackets (&lt;, &gt;) with &amp;lt; and &amp;gt; respectively, and replacing all
-     * interpolation start/end markers with their escaped counterparts.**
-     *
-     * Escaped interpolation markers are only replaced with the actual interpolation markers in rendered
-     * output when the $interpolate service processes the text. So, for HTML elements interpolated
-     * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter
-     * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,
-     * this is typically useful only when user-data is used in rendering a template from the server, or
-     * when otherwise untrusted data is used by a directive.
-     *
-     * <example>
-     *  <file name="index.html">
-     *    <div ng-init="username='A user'">
-     *      <p ng-init="apptitle='Escaping demo'">{{apptitle}}: \{\{ username = "defaced value"; \}\}
-     *        </p>
-     *      <p><strong>{{username}}</strong> attempts to inject code which will deface the
-     *        application, but fails to accomplish their task, because the server has correctly
-     *        escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash)
-     *        characters.</p>
-     *      <p>Instead, the result of the attempted script injection is visible, and can be removed
-     *        from the database by an administrator.</p>
-     *    </div>
-     *  </file>
-     * </example>
-     *
-     * @knownIssue
-     * It is currently not possible for an interpolated expression to contain the interpolation end
-     * symbol. For example, `{{ '}}' }}` will be incorrectly interpreted as `{{ ' }}` + `' }}`, i.e.
-     * an interpolated expression consisting of a single-quote (`'`) and the `' }}` string.
-     *
-     * @knownIssue
-     * All directives and components must use the standard `{{` `}}` interpolation symbols
-     * in their templates. If you change the application interpolation symbols the {@link $compile}
-     * service will attempt to denormalize the standard symbols to the custom symbols.
-     * The denormalization process is not clever enough to know not to replace instances of the standard
-     * symbols where they would not normally be treated as interpolation symbols. For example in the following
-     * code snippet the closing braces of the literal object will get incorrectly denormalized:
-     *
-     * ```
-     * <div data-context='{"context":{"id":3,"type":"page"}}">
-     * ```
-     *
-     * The workaround is to ensure that such instances are separated by whitespace:
-     * ```
-     * <div data-context='{"context":{"id":3,"type":"page"} }">
-     * ```

-      * Angular's wrapper for `window.setInterval`. The `fn` function is executed every `delay`
-      * milliseconds.
-      *
-      * The return value of registering an interval function is a promise. This promise will be
-      * notified upon each tick of the interval, and will be resolved after `count` iterations, or
-      * run indefinitely if `count` is not defined. The value of the notification will be the
-      * number of iterations that have run.
-      * To cancel an interval, call `$interval.cancel(promise)`.
-      *
-      * In tests you can use {@link ngMock.$interval#flush `$interval.flush(millis)`} to
-      * move forward by `millis` milliseconds and trigger any functions scheduled to run in that
-      * time.
-      *
-      * <div class="alert alert-warning">
-      * **Note**: Intervals created by this service must be explicitly destroyed when you are finished
-      * with them.  In particular they are not automatically destroyed when a controller's scope or a
-      * directive's element are destroyed.
-      * You should take this into consideration and make sure to always cancel the interval at the
-      * appropriate moment.  See the example below for more details on how and when to do this.
-      * </div>
-      *
-      * @param {function()} fn A function that should be called repeatedly.
-      * @param {number} delay Number of milliseconds between each function call.
-      * @param {number=} [count=0] Number of times to repeat. If not set, or 0, will repeat
-      *   indefinitely.
-      * @param {boolean=} [invokeApply=true] If set to `false` skips model dirty checking, otherwise
-      *   will invoke `fn` within the {@link ng.$rootScope.Scope#$apply $apply} block.
-      * @param {...*=} Pass additional parameters to the executed function.
-      * @returns {promise} A promise which will be notified on each iteration.

+// Sandboxing AngularJS Expressions
 // ------------------------------
-// Angular expressions are generally considered safe because these expressions only have direct
-// access to `$scope` and locals. However, one can obtain the ability to execute arbitrary JS code by
-// obtaining a reference to native JS functions such as the Function constructor.
+// AngularJS expressions are no longer sandboxed. So it is now even easier to access arbitrary JS code by
+// various means such as obtaining a reference to native JS functions like the Function constructor.
 //
-// As an example, consider the following Angular expression:
+// As an example, consider the following AngularJS expression:
 //
 //   {}.toString.constructor('alert("evil JS code")')
 //
-// This sandboxing technique is not perfect and doesn't aim to be. The goal is to prevent exploits
-// against the expression language, but not to prevent exploits that were enabled by exposing
-// sensitive JavaScript or browser APIs on Scope. Exposing such objects on a Scope is never a good
-// practice and therefore we are not even trying to protect against interaction with an object
-// explicitly exposed in this way.
-//
-// In general, it is not possible to access a Window object from an angular expression unless a
-// window or some DOM object that has a reference to window is published onto a Scope.
-// Similarly we prevent invocations of function known to be dangerous, as well as assignments to
-// native objects.
+// It is important to realize that if you create an expression from a string that contains user provided
+// content then it is possible that your application contains a security vulnerability to an XSS style attack.

+       * Suspend watchers of this scope subtree so that they will not be invoked during digest.
+       *
+       * This can be used to optimize your application when you know that running those watchers
+       * is redundant.
+       *
+       * **Warning**
+       *
+       * Suspending scopes from the digest cycle can have unwanted and difficult to debug results.
+       * Only use this approach if you are confident that you know what you are doing and have
+       * ample tests to ensure that bindings get updated as you expect.
+       *
+       * Some of the things to consider are:
+       *
+       * * Any external event on a directive/component will not trigger a digest while the hosting
+       *   scope is suspended - even if the event handler calls `$apply()` or `$rootScope.$digest()`.
+       * * Transcluded content exists on a scope that inherits from outside a directive but exists
+       *   as a child of the directive's containing scope. If the containing scope is suspended the
+       *   transcluded scope will also be suspended, even if the scope from which the transcluded
+       *   scope inherits is not suspended.
+       * * Multiple directives trying to manage the suspended status of a scope can confuse each other:
+       *    * A call to `$suspend()` on an already suspended scope is a no-op.
+       *    * A call to `$resume()` on a non-suspended scope is a no-op.
+       *    * If two directives suspend a scope, then one of them resumes the scope, the scope will no
+       *      longer be suspended. This could result in the other directive believing a scope to be
+       *      suspended when it is not.
+       * * If a parent scope is suspended then all its descendants will be also excluded from future
+       *   digests whether or not they have been suspended themselves. Note that this also applies to
+       *   isolate child scopes.
+       * * Calling `$digest()` directly on a descendant of a suspended scope will still run the watchers
+       *   for that scope and its descendants. When digesting we only check whether the current scope is
+       *   locally suspended, rather than checking whether it has a suspended ancestor.
+       * * Calling `$resume()` on a scope that has a suspended ancestor will not cause the scope to be
+       *   included in future digests until all its ancestors have been resumed.
+       * * Resolved promises, e.g. from explicit `$q` deferreds and `$http` calls, trigger `$apply()`
+       *   against the `$rootScope` and so will still trigger a global digest even if the promise was
+       *   initiated by a component that lives on a suspended scope.

  * The `$sceDelegateProvider` provider allows developers to configure the {@link ng.$sceDelegate

- * that the URLs used for sourcing Angular templates are safe.  Refer {@link

- * {@link ng.$sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider.resourceUrlBlacklist}

  *
- * For the general details about this service in Angular, read the main page for {@link ng.$sce
+ * The `$sceDelegateProvider` allows one to get/set the `trustedResourceUrlList` and
+ * `bannedResourceUrlList` used to ensure that the URLs used for sourcing AngularJS templates and
+ * other script-running URLs are safe (all places that use the `$sce.RESOURCE_URL` context). See

+ *
+ * For the general details about this service in AngularJS, read the main page for {@link ng.$sce
  * Strict Contextual Escaping (SCE)}.
  *
  * **Example**:  Consider the following case. <a name="example"></a>
  *
  * - your app is hosted at url `http://myapp.example.com/`
  * - but some of your templates are hosted on other domains you control such as
- *   `http://srv01.assets.example.com/`,  `http://srv02.assets.example.com/`, etc.
+ *   `http://srv01.assets.example.com/`, `http://srv02.assets.example.com/`, etc.
  * - and you have an open redirect at `http://myapp.example.com/clickThru?...`.
  *
  * Here is what a secure configuration for this scenario might look like:
  *
  * ```
  *  angular.module('myApp', []).config(function($sceDelegateProvider) {
- *    $sceDelegateProvider.resourceUrlWhitelist([
+ *    $sceDelegateProvider.trustedResourceUrlList([
  *      // Allow same origin resource loads.
  *      'self',
  *      // Allow loading from our assets domain.  Notice the difference between * and **.
  *      'http://srv*.assets.example.com/**'
  *    ]);
  *
- *    // The blacklist overrides the whitelist so the open redirect here is blocked.
- *    $sceDelegateProvider.resourceUrlBlacklist([
+ *    // The banned resource URL list overrides the trusted resource URL list so the open redirect
+ *    // here is blocked.
+ *    $sceDelegateProvider.bannedResourceUrlList([
  *      'http://myapp.example.com/clickThru**'
  *    ]);
  *  });
  * ```
+ * Note that an empty trusted resource URL list will block every resource URL from being loaded, and will require
+ * you to manually mark each one as trusted with `$sce.trustAsResourceUrl`. However, templates
+ * requested by {@link ng.$templateRequest $templateRequest} that are present in
+ * {@link ng.$templateCache $templateCache} will not go through this check. If you have a mechanism
+ * to populate your templates in that cache at config time, then it is a good idea to remove 'self'
+ * from the trusted resource URL lsit. This helps to mitigate the security impact of certain types
+ * of issues, like for instance attacker-controlled `ng-includes`.

+ * ## Strict Contextual Escaping
+ *
+ * Strict Contextual Escaping (SCE) is a mode in which AngularJS constrains bindings to only render
+ * trusted values. Its goal is to assist in writing code in a way that (a) is secure by default, and
+ * (b) makes auditing for security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
+ *
+ * ### Overview
  *
- * Strict Contextual Escaping (SCE) is a mode in which AngularJS requires bindings in certain
- * contexts to result in a value that is marked as safe to use for that context.  One example of
- * such a context is binding arbitrary html controlled by the user via `ng-bind-html`.  We refer
- * to these contexts as privileged or SCE contexts.
+ * To systematically block XSS security bugs, AngularJS treats all values as untrusted by default in
+ * HTML or sensitive URL bindings. When binding untrusted values, AngularJS will automatically
+ * run security checks on them (sanitizations, trusted URL resource, depending on context), or throw
+ * when it cannot guarantee the security of the result. That behavior depends strongly on contexts:
+ * HTML can be sanitized, but template URLs cannot, for instance.
  *
- * As of version 1.2, Angular ships with SCE enabled by default.
+ * To illustrate this, consider the `ng-bind-html` directive. It renders its value directly as HTML:
+ * we call that the *context*. When given an untrusted input, AngularJS will attempt to sanitize it
+ * before rendering if a sanitizer is available, and throw otherwise. To bypass sanitization and
+ * render the input as-is, you will need to mark it as trusted for that context before attempting
+ * to bind it.
  *
- * Note:  When enabled (the default), IE<11 in quirks mode is not supported.  In this mode, IE<11 allow
- * one to execute arbitrary javascript by the use of the expression() syntax.  Refer
- * <http://blogs.msdn.com/b/ie/archive/2008/10/16/ending-expressions.aspx> to learn more about them.
- * You can ensure your document is in standards mode and not quirks mode by adding `<!doctype html>`
- * to the top of your HTML document.
+ * As of version 1.2, AngularJS ships with SCE enabled by default.

+   * @ngdoc input
+   * @name input[range]
+   *
+   * @description
+   * Native range input with validation and transformation.
+   *
+   * The model for the range input must always be a `Number`.
+   *
+   * IE9 and other browsers that do not support the `range` type fall back
+   * to a text input without any default values for `min`, `max` and `step`. Model binding,
+   * validation and number parsing are nevertheless supported.
+   *
+   * Browsers that support range (latest Chrome, Safari, Firefox, Edge) treat `input[range]`
+   * in a way that never allows the input to hold an invalid value. That means:
+   * - any non-numerical value is set to `(max + min) / 2`.
+   * - any numerical value that is less than the current min val, or greater than the current max val
+   * is set to the min / max val respectively.
+   * - additionally, the current `step` is respected, so the nearest value that satisfies a step
+   * is used.
+   *
+   * See the [HTML Spec on input[type=range]](https://www.w3.org/TR/html5/forms.html#range-state-(type=range))
+   * for more info.
+   *
+   * This has the following consequences for AngularJS:
+   *
+   * Since the element value should always reflect the current model value, a range input
+   * will set the bound ngModel expression to the value that the browser has set for the
+   * input element. For example, in the following input `<input type="range" ng-model="model.value">`,
+   * if the application sets `model.value = null`, the browser will set the input to `'50'`.
+   * AngularJS will then set the model to `50`, to prevent input and model value being out of sync.
+   *
+   * That means the model for range will immediately be set to `50` after `ngModel` has been
+   * initialized. It also means a range input can never have the required error.
+   *
+   * This does not only affect changes to the model value, but also to the values of the `min`,
+   * `max`, and `step` attributes. When these change in a way that will cause the browser to modify
+   * the input value, AngularJS will also update the model value.
+   *
+   * Automatic value adjustment also means that a range input element can never have the `required`,
+   * `min`, or `max` errors.
+   *
+   * However, `step` is currently only fully implemented by Firefox. Other browsers have problems
+   * when the step value changes dynamically - they do not adjust the element value correctly, but
+   * instead may set the `stepMismatch` error. If that's the case, the AngularJS will set the `step`
+   * error on the input, and set the model to `undefined`.
+   *
+   * Note that `input[range]` is not compatible with`ngMax`, `ngMin`, and `ngStep`, because they do
+   * not set the `min` and `max` attributes, which means that the browser won't automatically adjust
+   * the input value based on their values, and will always assume min = 0, max = 100, and step = 1.
+   *
+   * @param {string}  ngModel Assignable AngularJS expression to data-bind to.
+   * @param {string=} name Property name of the form under which the control is published.
+   * @param {string=} min Sets the `min` validation to ensure that the value entered is greater
+   *                  than `min`. Can be interpolated.
+   * @param {string=} max Sets the `max` validation to ensure that the value entered is less than `max`.
+   *                  Can be interpolated.
+   * @param {string=} step Sets the `step` validation to ensure that the value entered matches the `step`
+   *                  Can be interpolated.
+   * @param {expression=} ngChange AngularJS expression to be executed when the ngModel value changes due
+   *                      to user interaction with the input element.
+   * @param {expression=} ngChecked If the expression is truthy, then the `checked` attribute will be set on the
+   *                      element. **Note** : `ngChecked` should not be used alongside `ngModel`.
+   *                      Checkout {@link ng.directive:ngChecked ngChecked} for usage.

- * element attribute, it makes the bindings invisible to the user while the page is loading.

- * An alternative solution to this problem would be using the

-/**
- * @ngdoc directive
- * @name ngClass
- * @restrict AC
- *
- * @description
- * The `ngClass` directive allows you to dynamically set CSS classes on an HTML element by databinding
- * an expression that represents all classes to be added.
- *
- * The directive operates in three different ways, depending on which of three types the expression
- * evaluates to:
- *
- * 1. If the expression evaluates to a string, the string should be one or more space-delimited class
- * names.
- *
- * 2. If the expression evaluates to an object, then for each key-value pair of the
- * object with a truthy value the corresponding key is used as a class name.
- *
- * 3. If the expression evaluates to an array, each element of the array should either be a string as in
- * type 1 or an object as in type 2. This means that you can mix strings and objects together in an array
- * to give you more control over what CSS classes appear. See the code below for an example of this.
- *
- *
- * The directive won't add duplicate classes if a particular class was already set.
- *
- * When the expression changes, the previously added classes are removed and only then are the
- * new classes added.
- *
- * @knownIssue
- * You should not use {@link guide/interpolation interpolation} in the value of the `class`
- * attribute, when using the `ngClass` directive on the same element.
- * See {@link guide/interpolation#known-issues here} for more info.
- *
- * @animations
- * | Animation                        | Occurs                              |
- * |----------------------------------|-------------------------------------|
- * | {@link ng.$animate#addClass addClass}       | just before the class is applied to the element   |
- * | {@link ng.$animate#removeClass removeClass} | just before the class is removed from the element |
- *
- * @element ANY
- * @param {expression} ngClass {@link guide/expression Expression} to eval. The result
- *   of the evaluation can be a string representing space delimited class
- *   names, an array, or a map of class names to boolean values. In the case of a map, the
- *   names of the properties whose values are truthy will be added as css classes to the
- *   element.
- *
- * @example Example that demonstrates basic bindings via ngClass directive.

-   ## Animations
-
-   The example below demonstrates how to perform animations using ngClass.
-
-   <example module="ngAnimate" deps="angular-animate.js" animations="true">
-     <file name="index.html">
-      <input id="setbtn" type="button" value="set" ng-click="myVar='my-class'">
-      <input id="clearbtn" type="button" value="clear" ng-click="myVar=''">
-      <br>
-      <span class="base-class" ng-class="myVar">Sample Text</span>
-     </file>
-     <file name="style.css">
-       .base-class {
-         transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;
-       }
-
-       .base-class.my-class {
-         color: red;
-         font-size:3em;
-       }
-     </file>
-     <file name="protractor.js" type="protractor">
-       it('should check ng-class', function() {
-         expect(element(by.css('.base-class')).getAttribute('class')).not.
-           toMatch(/my-class/);
-
-         element(by.id('setbtn')).click();
-
-         expect(element(by.css('.base-class')).getAttribute('class')).
-           toMatch(/my-class/);
-
-         element(by.id('clearbtn')).click();
-
-         expect(element(by.css('.base-class')).getAttribute('class')).not.
-           toMatch(/my-class/);
-       });
-     </file>
-   </example>
-
-
-   ## ngClass and pre-existing CSS3 Transitions/Animations
-   The ngClass directive still supports CSS3 Transitions/Animations even if they do not follow the ngAnimate CSS naming structure.
-   Upon animation ngAnimate will apply supplementary CSS classes to track the start and end of an animation, but this will not hinder
-   any pre-existing CSS transitions already on the element. To get an idea of what happens during a class-based animation, be sure
-   to view the step by step details of {@link $animate#addClass $animate.addClass} and
-   {@link $animate#removeClass $animate.removeClass}.

- * @restrict AC
- *
- * @description
- * The `ngCloak` directive is used to prevent the Angular html template from being briefly
- * displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
- * directive to avoid the undesirable flicker effect caused by the html template display.
- *
- * The directive can be applied to the `<body>` element, but the preferred usage is to apply
- * multiple `ngCloak` directives to small portions of the page to permit progressive rendering
- * of the browser view.
- *
- * `ngCloak` works in cooperation with the following css rule embedded within `angular.js` and
- * `angular.min.js`.
- * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
- *
- * ```css
- * [ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
- *   display: none !important;
- * }
- * ```
- *
- * When this css rule is loaded by the browser, all html elements (including their children) that
- * are tagged with the `ngCloak` directive are hidden. When Angular encounters this directive
- * during the compilation of the template it deletes the `ngCloak` element attribute, making
- * the compiled element visible.
- *
- * For the best result, the `angular.js` script must be loaded in the head section of the html
- * document; alternatively, the css rule above must be included in the external stylesheet of the
- * application.

-/**
- * @ngdoc directive
- * @name ngController
- *
- * @description
- * The `ngController` directive attaches a controller class to the view. This is a key aspect of how angular
- * supports the principles behind the Model-View-Controller design pattern.
- *
- * MVC components in angular:
- *
- * * Model — Models are the properties of a scope; scopes are attached to the DOM where scope properties
- *   are accessed through bindings.
- * * View — The template (HTML with data bindings) that is rendered into the View.
- * * Controller — The `ngController` directive specifies a Controller class; the class contains business
- *   logic behind the application to decorate the scope with functions and values
- *
- * Note that you can also attach controllers to the DOM by declaring it in a route definition
- * via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller
- * again using `ng-controller` in the template itself.  This will cause the controller to be attached
- * and executed twice.
- *
- * @element ANY
- * @scope
- * @priority 500
- * @param {expression} ngController Name of a constructor function registered with the current
- * {@link ng.$controllerProvider $controllerProvider} or an {@link guide/expression expression}
- * that on the current scope evaluates to a constructor function.
- *
- * The controller instance can be published into a scope property by specifying
- * `ng-controller="as propertyName"`.
- *
- * If the current `$controllerProvider` is configured to use globals (via
- * {@link ng.$controllerProvider#allowGlobals `$controllerProvider.allowGlobals()` }), this may
- * also be the name of a globally accessible constructor function (not recommended).
- *
- * @example
- * Here is a simple form for editing user contact information. Adding, removing, clearing, and
- * greeting are methods declared on the controller (see source tab). These methods can
- * easily be called from the angular markup. Any changes to the data are automatically reflected
- * in the View without the need for a manual update.
- *
- * Two different declaration styles are included below:
- *
- * * one binds methods and properties directly onto the controller using `this`:
- * `ng-controller="SettingsController1 as settings"`
- * * one injects `$scope` into the controller:
- * `ng-controller="SettingsController2"`
- *
- * The second option is more common in the Angular community, and is generally used in boilerplates
- * and in this guide. However, there are advantages to binding properties directly to the controller
- * and avoiding scope.
- *
- * * Using `controller as` makes it obvious which controller you are accessing in the template when
- * multiple controllers apply to an element.
- * * If you are writing your controllers as classes you have easier access to the properties and
- * methods, which will appear on the scope, from inside the controller code.
- * * Since there is always a `.` in the bindings, you don't have to worry about prototypal
- * inheritance masking primitives.
- *
- * This example demonstrates the `controller as` syntax.
- *
- * <example name="ngControllerAs" module="controllerAsExample">
- *   <file name="index.html">
- *    <div id="ctrl-as-exmpl" ng-controller="SettingsController1 as settings">

- * @ngdoc directive
- * @name ngCsp
- *
- * @element html
- * @description
- *
- * Angular has some features that can break certain
- * [CSP (Content Security Policy)](https://developer.mozilla.org/en/Security/CSP) rules.
- *
- * If you intend to implement these rules then you must tell Angular not to use these features.
- *
- * This is necessary when developing things like Google Chrome Extensions or Universal Windows Apps.
- *
- *
- * The following rules affect Angular:
- *
- * * `unsafe-eval`: this rule forbids apps to use `eval` or `Function(string)` generated functions
- * (among other things). Angular makes use of this in the {@link $parse} service to provide a 30%
- * increase in the speed of evaluating Angular expressions.
- *
- * * `unsafe-inline`: this rule forbids apps from inject custom styles into the document. Angular
- * makes use of this to include some CSS rules (e.g. {@link ngCloak} and {@link ngHide}).
- * To make these directives work when a CSP rule is blocking inline styles, you must link to the
- * `angular-csp.css` in your HTML manually.
- *
- * If you do not provide `ngCsp` then Angular tries to autodetect if CSP is blocking unsafe-eval
- * and automatically deactivates this feature in the {@link $parse} service. This autodetection,
- * however, triggers a CSP error to be logged in the console:
- *
- * ```
- * Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of
- * script in the following Content Security Policy directive: "default-src 'self'". Note that
- * 'script-src' was not explicitly set, so 'default-src' is used as a fallback.
- * ```
- *
- * This error is harmless but annoying. To prevent the error from showing up, put the `ngCsp`
- * directive on an element of the HTML document that appears before the `<script>` tag that loads
- * the `angular.js` file.
- *
- * *Note: This directive is only available in the `ng-csp` and `data-ng-csp` attribute form.*
- *
- * You can specify which of the CSP related Angular features should be deactivated by providing
- * a value for the `ng-csp` attribute. The options are as follows:
- *
- * * no-inline-style: this stops Angular from injecting CSS styles into the DOM
- *
- * * no-unsafe-eval: this stops Angular from optimizing $parse with unsafe eval of strings
- *
- * You can use these values in the following combinations:
- *
- *
- * * No declaration means that Angular will assume that you can do inline styles, but it will do
- * a runtime check for unsafe-eval. E.g. `<body>`. This is backwardly compatible with previous versions
- * of Angular.
- *
- * * A simple `ng-csp` (or `data-ng-csp`) attribute will tell Angular to deactivate both inline
- * styles and unsafe eval. E.g. `<body ng-csp>`. This is backwardly compatible with previous versions
- * of Angular.
- *
- * * Specifying only `no-unsafe-eval` tells Angular that we must not use eval, but that we can inject
- * inline styles. E.g. `<body ng-csp="no-unsafe-eval">`.
- *
- * * Specifying only `no-inline-style` tells Angular that we must not inject styles, but that we can
- * run eval - no automatic check for unsafe eval will occur. E.g. `<body ng-csp="no-inline-style">`
- *
- * * Specifying both `no-unsafe-eval` and `no-inline-style` tells Angular that we must not inject
- * styles nor use eval, which is the same as an empty: ng-csp.
- * E.g.`<body ng-csp="no-inline-style;no-unsafe-eval">`
- *
- * @example
- * This example shows how to apply the `ngCsp` directive to the `html` tag.
-   ```html
-     <!doctype html>
-     <html ng-app ng-csp>
-     ...
-     ...
-     </html>
-   ```
-  * @example
-      // Note: the suffix `.csp` in the example name triggers
-      // csp mode in our http server!
-      <example name="example.csp" module="cspExample" ng-csp="true">
-        <file name="index.html">

- * element in the DOM rather than changing its visibility via the `display` css property.  A common
- * case when this difference is significant is when using css selectors that rely on an element's
- * position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes.
- *
- * Note that when an element is removed using `ngIf` its scope is destroyed and a new scope
- * is created when the element is restored.  The scope created within `ngIf` inherits from
- * its parent scope using
- * [prototypal inheritance](https://github.com/angular/angular.js/wiki/Understanding-Scopes#javascript-prototypal-inheritance).
- * An important implication of this is if `ngModel` is used within `ngIf` to bind to
- * a javascript primitive defined in the parent scope. In this case any modifications made to the
- * variable within the child scope will override (hide) the value in the parent scope.
- *
- * Also, `ngIf` recreates elements using their compiled state. An example of this behavior
- * is if an element's class attribute is directly modified after it's compiled, using something like
- * jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element
- * the added class will be lost because the original compiled state is used to regenerate the element.
- *
- * Additionally, you can provide animations via the `ngAnimate` module to animate the `enter`
- * and `leave` effects.
- *
- * @animations
- * | Animation                        | Occurs                               |
- * |----------------------------------|-------------------------------------|
- * | {@link ng.$animate#enter enter}  | just after the `ngIf` contents change and a new DOM element is created and injected into the `ngIf` container |
- * | {@link ng.$animate#leave leave}  | just before the `ngIf` contents are removed from the DOM |
- *
- * @element ANY
- * @scope
- * @priority 600
- * @param {expression} ngIf If the {@link guide/expression expression} is falsy then
- *     the element is removed from the DOM tree. If it is truthy a copy of the compiled
- *     element is added to the DOM tree.
- *
- * @example
-  <example module="ngAnimate" deps="angular-animate.js" animations="true">
-    <file name="index.html">

- * Fetches, compiles and includes an external HTML fragment.
- *
- * By default, the template URL is restricted to the same domain and protocol as the
- * application document. This is done by calling {@link $sce#getTrustedResourceUrl
- * $sce.getTrustedResourceUrl} on it. To load templates from other domains or protocols
- * you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist them} or
- * {@link $sce#trustAsResourceUrl wrap them} as trusted values. Refer to Angular's {@link
- * ng.$sce Strict Contextual Escaping}.
- *
- * In addition, the browser's
- * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
- * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
- * policy may further restrict whether the template is successfully loaded.
- * For example, `ngInclude` won't work for cross-domain requests on all browsers and for `file://`
- * access on some browsers.
- *
- * @animations

- * The enter and leave animation occur concurrently.

- *
- * @param {string} ngInclude|src angular expression evaluating to URL. If the source is a string constant,
- *                 make sure you wrap it in **single** quotes, e.g. `src="'myPartialTemplate.html'"`.
- * @param {string=} onload Expression to evaluate when a new partial is loaded.
- *                  <div class="alert alert-warning">
- *                  **Note:** When using onload on SVG elements in IE11, the browser will try to call
- *                  a function with the name on the window element, which will usually throw a
- *                  "function is undefined" error. To fix this, you can instead use `data-onload` or a

- * is set.
- * @property {*} $modelValue The value in the model that the control is bound to.
- * @property {Array.<Function>} $parsers Array of functions to execute, as a pipeline, whenever

-       {@link ngModel.NgModelController#$validators `$validators`} collection.
-
-Parsers are used to sanitize / convert the {@link ngModel.NgModelController#$viewValue
-`$viewValue`}.
-
-Returning `undefined` from a parser means a parse error occurred. In that case,
-no {@link ngModel.NgModelController#$validators `$validators`} will run and the `ngModel`
-will be set to `undefined` unless {@link ngModelOptions `ngModelOptions.allowInvalid`}
-is set to `true`. The parse error is stored in `ngModel.$error.parse`.
-
- *
- * @property {Array.<Function>} $formatters Array of functions to execute, as a pipeline, whenever
-       the model value changes. The functions are called in reverse array order, each passing the value through to the
-       next. The last return value is used as the actual DOM value.
-       Used to format / convert values for display in the control.
- * ```js

- *     return value.toUpperCase();
- *   }
- * }
- * ngModel.$formatters.push(formatter);
- * ```
- *
- * @property {Object.<string, function>} $validators A collection of validators that are applied
- *      whenever the model value changes. The key value within the object refers to the name of the
- *      validator while the function refers to the validation operation. The validation operation is
- *      provided with the model value as an argument and must return a true or false value depending
- *      on the response of that validation.
- *
- * ```js
- * ngModel.$validators.validCharacters = function(modelValue, viewValue) {
- *   var value = modelValue || viewValue;
- *   return /[0-9]+/.test(value) &&

- *
- * @property {Object.<string, function>} $asyncValidators A collection of validations that are expected to
- *      perform an asynchronous validation (e.g. a HTTP request). The validation function that is provided
- *      is expected to return a promise when it is run during the model validation process. Once the promise
- *      is delivered then the validation status will be set to true when fulfilled and false when rejected.
- *      When the asynchronous validators are triggered, each of the validators will run in parallel and the model
- *      value will only be updated once all validators have been fulfilled. As long as an asynchronous validator
- *      is unfulfilled, its key will be added to the controllers `$pending` property. Also, all asynchronous validators
- *      will only run once all synchronous validators have passed.
- *
- * Please note that if $http is used then it is important that the server returns a success HTTP response code
- * in order to fulfill the validation and a status level of `4xx` in order to reject the validation.
- *
- * ```js
- * ngModel.$asyncValidators.uniqueUsername = function(modelValue, viewValue) {

- * @property {boolean} $invalid True if at least one error on the control.
- * @property {string} $name The name attribute of the control.

- * @description
- *
- * `NgModelController` provides API for the {@link ngModel `ngModel`} directive.
- * The controller contains services for data-binding, validation, CSS updates, and value formatting
- * and parsing. It purposefully does not contain any logic which deals with DOM rendering or
- * listening to DOM events.
- * Such DOM related logic should be provided by other directives which make use of
- * `NgModelController` for data-binding to control elements.
- * Angular provides this DOM logic for most {@link input `input`} elements.
- * At the end of this page you can find a {@link ngModel.NgModelController#custom-control-example
- * custom control example} that uses `ngModelController` to bind to `contenteditable` elements.
- *
- * @example
- * ### Custom Control Example
- * This example shows how to use `NgModelController` with a custom control to achieve
- * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
- * collaborate together to achieve the desired result.
- *
- * `contenteditable` is an HTML5 attribute, which tells the browser to let the element
- * contents be edited in place by the user.
- *
- * We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize}
- * module to automatically remove "bad" content like inline event listener (e.g. `<span onclick="...">`).
- * However, as we are using `$sce` the model can still decide to provide unsafe content if it marks
- * that content using the `$sce` service.
- *
- * <example name="NgModelController" module="customControl" deps="angular-sanitize.js">
-    <file name="style.css">
-      [contenteditable] {
-        border: 1px solid black;
-        background-color: white;
-        min-height: 20px;
-      }
-
-      .ng-invalid {
-        border: 1px solid red;
-      }
-
-    </file>
-    <file name="script.js">
-      angular.module('customControl', ['ngSanitize']).
-        directive('contenteditable', ['$sce', function($sce) {
-          return {
-            restrict: 'A', // only activate on element attribute
-            require: '?ngModel', // get a hold of NgModelController

-   * Cancel an update and reset the input element's value to prevent an update to the `$modelValue`,
-   * which may be caused by a pending debounced event or because the input is waiting for a some
-   * future event.
-   *
-   * If you have an input that uses `ng-model-options` to set up debounced updates or updates that
-   * depend on special events such as blur, you can have a situation where there is a period when
-   * the `$viewValue` is out of sync with the ngModel's `$modelValue`.
-   *
-   * In this case, you can use `$rollbackViewValue()` to manually cancel the debounced / future update
-   * and reset the input to the last committed view value.
-   *
-   * It is also possible that you run into difficulties if you try to update the ngModel's `$modelValue`
-   * programmatically before these debounced/future events have resolved/occurred, because Angular's
-   * dirty checking mechanism is not able to tell whether the model has actually changed or not.
-   *
-   * The `$rollbackViewValue()` method should be called before programmatically changing the model of an
-   * input which may have such events pending. This is important in order to make sure that the
-   * input field will be updated with the new model value and any pending operations are cancelled.

-   * Update the view value.
-   *
-   * This method should be called when a control wants to change the view value; typically,
-   * this is done from within a DOM event handler. For example, the {@link ng.directive:input input}
-   * directive calls it when the value of the input changes and {@link ng.directive:select select}
-   * calls it when an option is selected.
-   *
-   * When `$setViewValue` is called, the new `value` will be staged for committing through the `$parsers`
-   * and `$validators` pipelines. If there are no special {@link ngModelOptions} specified then the staged
-   * value sent directly for processing, finally to be applied to `$modelValue` and then the
-   * **expression** specified in the `ng-model` attribute. Lastly, all the registered change listeners,
-   * in the `$viewChangeListeners` list, are called.
-   *
-   * In case the {@link ng.directive:ngModelOptions ngModelOptions} directive is used with `updateOn`
-   * and the `default` trigger is not listed, all those actions will remain pending until one of the
-   * `updateOn` events is triggered on the DOM element.
-   * All these actions will be debounced if the {@link ng.directive:ngModelOptions ngModelOptions}
-   * directive is used with a custom debounce for this particular event.
-   * Note that a `$digest` is only triggered once the `updateOn` events are fired, or if `debounce`
-   * is specified, once the timer runs out.
-   *
-   * When used with standard inputs, the view value will always be a string (which is in some cases
-   * parsed into another type, such as a `Date` object for `input[date]`.)
-   * However, custom controls might also pass objects to this method. In this case, we should make
-   * a copy of the object before passing it to `$setViewValue`. This is because `ngModel` does not
-   * perform a deep watch of objects, it only looks for a change of identity. If you only change
-   * the property of the object then ngModel will not realize that the object has changed and
-   * will not invoke the `$parsers` and `$validators` pipelines. For this reason, you should
-   * not change properties of the copy once it has been passed to `$setViewValue`.
-   * Otherwise you may cause the model value on the scope to change incorrectly.
-   *
-   * <div class="alert alert-info">
-   * In any case, the value passed to the method should always reflect the current value
-   * of the control. For example, if you are calling `$setViewValue` for an input element,
-   * you should pass the input DOM value. Otherwise, the control and the scope model become
-   * out of sync. It's also important to note that `$setViewValue` does not call `$render` or change
-   * the control's DOM value in any way. If we want to change the control's DOM value
-   * programmatically, we should update the `ngModel` scope expression. Its new value will be
-   * picked up by the model controller, which will run it through the `$formatters`, `$render` it
-   * to update the DOM, and finally call `$validate` on it.

- * @ngdoc directive
- * @name ngModel
- *
- * @element input
- * @priority 1
- *
- * @description
- * The `ngModel` directive binds an `input`,`select`, `textarea` (or custom form control) to a
- * property on the scope using {@link ngModel.NgModelController NgModelController},
- * which is created and exposed by this directive.
- *
- * `ngModel` is responsible for:
- *
- * - Binding the view into the model, which other directives such as `input`, `textarea` or `select`
- *   require.
- * - Providing validation behavior (i.e. required, number, email, url).
- * - Keeping the state of the control (valid/invalid, dirty/pristine, touched/untouched, validation errors).
- * - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`, `ng-touched`,
- *   `ng-untouched`, `ng-empty`, `ng-not-empty`) including animations.
- * - Registering the control with its parent {@link ng.directive:form form}.
- *
- * Note: `ngModel` will try to bind to the property given by evaluating the expression on the
- * current scope. If the property doesn't already exist on this scope, it will be created
- * implicitly and added to the scope.
- *
- * For best practices on using `ngModel`, see:
- *
- *  - [Understanding Scopes](https://github.com/angular/angular.js/wiki/Understanding-Scopes)
- *
- * For basic examples, how to use `ngModel`, see:
- *
- *  - {@link ng.directive:input input}
- *    - {@link input[text] text}
- *    - {@link input[checkbox] checkbox}
- *    - {@link input[radio] radio}
- *    - {@link input[number] number}
- *    - {@link input[email] email}
- *    - {@link input[url] url}
- *    - {@link input[date] date}
- *    - {@link input[datetime-local] datetime-local}
- *    - {@link input[time] time}
- *    - {@link input[month] month}
- *    - {@link input[week] week}
- *  - {@link ng.directive:select select}
- *  - {@link ng.directive:textarea textarea}
- *
- * # Complex Models (objects or collections)
- *
- * By default, `ngModel` watches the model by reference, not value. This is important to know when
- * binding inputs to models that are objects (e.g. `Date`) or collections (e.g. arrays). If only properties of the
- * object or collection change, `ngModel` will not be notified and so the input will not be  re-rendered.
- *
- * The model must be assigned an entirely new object or collection before a re-rendering will occur.
- *
- * Some directives have options that will cause them to use a custom `$watchCollection` on the model expression
- * - for example, `ngOptions` will do so when a `track by` clause is included in the comprehension expression or
- * if the select is given the `multiple` attribute.
- *
- * The `$watchCollection()` method only does a shallow comparison, meaning that changing properties deeper than the
- * first level of the object (or only changing the properties of an item in the collection if it's an array) will still
- * not trigger a re-rendering of the model.
- *
- * # CSS classes
- * The following CSS classes are added and removed on the associated input/select/textarea element
- * depending on the validity of the model.
- *
- *  - `ng-valid`: the model is valid
- *  - `ng-invalid`: the model is invalid
- *  - `ng-valid-[key]`: for each valid key added by `$setValidity`
- *  - `ng-invalid-[key]`: for each invalid key added by `$setValidity`
- *  - `ng-pristine`: the control hasn't been interacted with yet
- *  - `ng-dirty`: the control has been interacted with
- *  - `ng-touched`: the control has been blurred
- *  - `ng-untouched`: the control hasn't been blurred
- *  - `ng-pending`: any `$asyncValidators` are unfulfilled
- *  - `ng-empty`: the view does not contain a value or the value is deemed "empty", as defined
- *     by the {@link ngModel.NgModelController#$isEmpty} method
- *  - `ng-not-empty`: the view contains a non-empty value
- *
- * Keep in mind that ngAnimate can detect each of these classes when added and removed.
- *
- * ## Animation Hooks
- *
- * Animations within models are triggered when any of the associated CSS classes are added and removed
- * on the input element which is attached to the model. These classes include: `.ng-pristine`, `.ng-dirty`,
- * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.
- * The animations that are triggered within ngModel are similar to how they work in ngClass and
- * animations can be hooked into using CSS transitions, keyframes as well as JS animations.
- *
- * The following example shows a simple way to utilize CSS transitions to style an input element
- * that has been rendered as invalid after it has been validated:
- *
- * <pre>
- * //be sure to include ngAnimate as a module to hook into more
- * //advanced animations
- * .my-input {
- *   transition:0.5s linear all;
- *   background: white;
- * }
- * .my-input.ng-invalid {
- *   background: red;
- *   color:white;
- * }
- * </pre>
- *
- * @example
- * <example deps="angular-animate.js" animations="true" fixBase="true" module="inputExample">
-     <file name="index.html">
-       <script>
-        angular.module('inputExample', [])
-          .controller('ExampleController', ['$scope', function($scope) {
-            $scope.val = '1';
-          }]);
-       </script>
-       <style>
-         .my-input {
-           transition:all linear 0.5s;
-           background: transparent;
-         }
-         .my-input.ng-invalid {
-           color:white;
-           background: red;
-         }
-       </style>
-       <p id="inputDescription">
-        Update input to see transitions when valid/invalid.
-        Integer is a valid value.
-       </p>
-       <form name="testForm" ng-controller="ExampleController">
-         <input ng-model="val" ng-pattern="/^\d+$/" name="anim" class="my-input"
-                aria-describedby="inputDescription" />
-       </form>
-     </file>
- * </example>
- *
- * ## Binding to a getter/setter
- *
- * Sometimes it's helpful to bind `ngModel` to a getter/setter function.  A getter/setter is a
- * function that returns a representation of the model when called with zero arguments, and sets
- * the internal state of a model when called with an argument. It's sometimes useful to use this
- * for models that have an internal representation that's different from what the model exposes
- * to the view.
- *
- * <div class="alert alert-success">
- * **Best Practice:** It's best to keep getters fast because Angular is likely to call them more
- * frequently than other parts of your code.
- * </div>
- *
- * You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that
- * has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to
- * a `<form>`, which will enable this behavior for all `<input>`s within it. See
- * {@link ng.directive:ngModelOptions `ngModelOptions`} for more.
- *
- * The following example shows how to use `ngModel` with a getter/setter:
- *
- * @example
- * <example name="ngModel-getter-setter" module="getterSetterExample">
-     <file name="index.html">
-       <div ng-controller="ExampleController">
-         <form name="userForm">
-           <label>Name:
-             <input type="text" name="userName"
-                    ng-model="user.name"
-                    ng-model-options="{ getterSetter: true }" />
-           </label>
-         </form>
-         <pre>user.name = <span ng-bind="user.name()"></span></pre>
-       </div>
-     </file>
-     <file name="app.js">
-       angular.module('getterSetterExample', [])
-         .controller('ExampleController', ['$scope', function($scope) {
-           var _name = 'Brian';
-           $scope.user = {
-             name: function(newName) {
-              // Note that newName can be undefined for two reasons:
-              // 1. Because it is called as a getter and thus called with no arguments
-              // 2. Because the property should actually be set to undefined. This happens e.g. if the
-              //    input is invalid
-              return arguments.length ? (_name = newName) : _name;
-             }
-           };

-/**
- * @ngdoc directive
- * @name ngModelOptions
- *
- * @description
- * Allows tuning how model updates are done. Using `ngModelOptions` you can specify a custom list of
- * events that will trigger a model update and/or a debouncing delay so that the actual update only
- * takes place when a timer expires; this timer will be reset after another change takes place.
- *
- * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might
- * be different from the value in the actual model. This means that if you update the model you
- * should also invoke {@link ngModel.NgModelController `$rollbackViewValue`} on the relevant input field in
- * order to make sure it is synchronized with the model and that any debounced action is canceled.
- *
- * The easiest way to reference the control's {@link ngModel.NgModelController `$rollbackViewValue`}
- * method is by making sure the input is placed inside a form that has a `name` attribute. This is
- * important because `form` controllers are published to the related scope under the name in their
- * `name` attribute.
- *
- * Any pending changes will take place immediately when an enclosing form is submitted via the
- * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
- * to have access to the updated model.
- *
- * `ngModelOptions` has an effect on the element it's declared on and its descendants.
- *
- * @param {Object} ngModelOptions options to apply to the current model. Valid keys are:
- *   - `updateOn`: string specifying which event should the input be bound to. You can set several
- *     events using an space delimited list. There is a special event called `default` that
- *     matches the default events belonging of the control.
- *   - `debounce`: integer value which contains the debounce model update value in milliseconds. A
- *     value of 0 triggers an immediate update. If an object is supplied instead, you can specify a
- *     custom value for each event. For example:
- *     `ng-model-options="{ updateOn: 'default blur', debounce: { 'default': 500, 'blur': 0 } }"`
- *   - `allowInvalid`: boolean value which indicates that the model can be set with values that did
- *     not validate correctly instead of the default behavior of setting the model to undefined.
- *   - `getterSetter`: boolean value which determines whether or not to treat functions bound to
-       `ngModel` as getters/setters.
- *   - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for
- *     `<input type="date">`, `<input type="time">`, ... . It understands UTC/GMT and the
- *     continental US time zone abbreviations, but for general use, use a time zone offset, for
- *     example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
- *     If not specified, the timezone of the browser will be used.
- *
- * @example
-
-  The following example shows how to override immediate updates. Changes on the inputs within the
-  form will update the model only when the control loses focus (blur event). If `escape` key is
-  pressed while the input field is focused, the value is reset to the value in the current model.

- * @element ANY
+ * The `ngNonBindable` directive tells AngularJS not to compile or bind the contents of the current

+ * and bindings but which should be ignored by AngularJS. This could be the case if you have a site

+ *
+ * When using {@link ngShow} and / or {@link ngHide} to toggle between elements, it can
+ * happen that both the element to show and the element to hide are visible for a very short time.
+ *
+ * This usually happens when the {@link ngAnimate ngAnimate module} is included, but no actual animations

  *
- * By default, the `.ng-hide` class will style the element with `display: none!important`. If you wish to change

  * @description
- * The controller for the `<select>` directive. This provides support for reading
- * and writing the selected value(s) of the control and also coordinates dynamically
- * added `<option>` elements, perhaps by an `ngRepeat` directive.
+ * The controller for the {@link ng.select select} directive. The controller exposes
+ * a few utility methods that can be used to augment the behavior of a regular or an
+ * {@link ng.ngOptions ngOptions} select element.
+ *
+ * @example
+ * ### Set a custom error when the unknown option is selected
+ *
+ * This example sets a custom error "unknownValue" on the ngModelController
+ * when the select element's unknown option is selected, i.e. when the model is set to a value
+ * that is not matched by any option.
+ *
+ * <example name="select-unknown-value-error" module="staticSelect">
+ * <file name="index.html">
+ * <div ng-controller="ExampleController">
+ *   <form name="myForm">
+ *     <label for="testSelect"> Single select: </label><br>

+ *       Error: The current model doesn't match any option</span><br>

+ * ### Set the "required" error when the unknown option is selected.
+ *
+ * By default, the "required" error on the ngModelController is only set on a required select
+ * when the empty option is selected. This example adds a custom directive that also sets the
+ * error when the unknown option is selected.

- * **DEPRECATION NOTICE**: Beginning with Angular 1.5, this directive is deprecated and by default **disabled**.
- * The directive will receive no further support and might be removed from future releases.
- * If you need the directive, you can enable it with the {@link ngTouch.$touchProvider $touchProvider#ngClickOverrideEnabled}
- * function. We also recommend that you migrate to [FastClick](https://github.com/ftlabs/fastclick).
- * To learn more about the 300ms delay, this [Telerik article](http://developer.telerik.com/featured/300-ms-click-delay-ios-8/)
- * gives a good overview.
- * </div>
- * A more powerful replacement for the default ngClick designed to be used on touchscreen
- * devices. Most mobile browsers wait about 300ms after a tap-and-release before sending
- * the click event. This version handles them immediately, and then prevents the
- * following click event from propagating.
- *
- * Requires the {@link ngTouch `ngTouch`} module to be installed.
- *
- * This directive can fall back to using an ordinary click event, and so works on desktop
- * browsers as well as mobile.
- *
- * This directive also sets the CSS class `ng-click-active` while the element is being held
- * down (by a mouse click or touch) so you can restyle the depressed element if you wish.

-  // TAP EVENTS AND GHOST CLICKS
-  //
-  // Why tap events?
-  // Mobile browsers detect a tap, then wait a moment (usually ~300ms) to see if you're
-  // double-tapping, and then fire a click event.
-  //
-  // This delay sucks and makes mobile apps feel unresponsive.
-  // So we detect touchstart, touchcancel and touchend ourselves and determine when
-  // the user has tapped on something.
-  //
-  // What happens when the browser then generates a click event?
-  // The browser, of course, also detects the tap and fires a click after a delay. This results in
-  // tapping/clicking twice. We do "clickbusting" to prevent it.
-  //
-  // How does it work?
-  // We attach global touchstart and click handlers, that run during the capture (early) phase.
-  // So the sequence for a tap is:
-  // - global touchstart: Sets an "allowable region" at the point touched.
-  // - element's touchstart: Starts a touch
-  // (- touchcancel ends the touch, no click follows)
-  // - element's touchend: Determines if the tap is valid (didn't move too far away, didn't hold
-  //   too long) and fires the user's tap handler. The touchend also calls preventGhostClick().
-  // - preventGhostClick() removes the allowable region the global touchstart created.
-  // - The browser generates a click event.
-  // - The global click handler catches the click, and checks whether it was in an allowable region.
-  //     - If preventGhostClick was called, the region will have been removed, the click is busted.
-  //     - If the region is still there, the click proceeds normally. Therefore clicks on links and
-  //       other elements without ngTap on them work normally.
-  //
-  // This is an ugly, terrible hack!
-  // Yeah, tell me about it. The alternatives are using the slow click events, or making our users
-  // deal with the ghost clicks, so I consider this the least of evils. Fortunately Angular
-  // encapsulates this ugly logic away from the user.
-  //
-  // Why not just put click handlers on the element?
-  // We do that too, just to be sure. If the tap event caused the DOM to change,
-  // it is possible another element is now in that position. To take account for these possibly
-  // distinct elements, the handlers are global and care only about coordinates.

- *
- * @description
- * Compiles an HTML string or DOM into a template and produces a template function, which
- * can then be used to link {@link ng.$rootScope.Scope `scope`} and the template together.
- *
- * The compilation is a process of walking the DOM tree and matching DOM elements to
- * {@link ng.$compileProvider#directive directives}.
- *
- * <div class="alert alert-warning">
- * **Note:** This document is an in-depth reference of all directive options.
- * For a gentle introduction to directives with examples of common use cases,
- * see the {@link guide/directive directive guide}.
- * </div>
- *
- * ## Comprehensive Directive API
- *
- * There are many different options for a directive.
- *
- * The difference resides in the return value of the factory function.
- * You can either return a {@link $compile#directive-definition-object Directive Definition Object (see below)}
- * that defines the directive properties, or just the `postLink` function (all other properties will have
- * the default values).
- *
- * <div class="alert alert-success">
- * **Best Practice:** It's recommended to use the "directive definition object" form.
- * </div>
- *
- * Here's an example directive declared with a Directive Definition Object:
- *
- * ```js
- *   var myModule = angular.module(...);
- *
- *   myModule.directive('directiveName', function factory(injectables) {
- *     var directiveDefinitionObject = {
- *       priority: 0,
- *       template: '<div></div>', // or // function(tElement, tAttrs) { ... },
- *       // or
- *       // templateUrl: 'directive.html', // or // function(tElement, tAttrs) { ... },
- *       transclude: false,
- *       restrict: 'A',
- *       templateNamespace: 'html',
- *       scope: false,
- *       controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
- *       controllerAs: 'stringIdentifier',
- *       bindToController: false,
- *       require: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],
- *       compile: function compile(tElement, tAttrs, transclude) {
- *         return {
- *           pre: function preLink(scope, iElement, iAttrs, controller) { ... },
- *           post: function postLink(scope, iElement, iAttrs, controller) { ... }
- *         }
- *         // or
- *         // return function postLink( ... ) { ... }
- *       },
- *       // or
- *       // link: {
- *       //  pre: function preLink(scope, iElement, iAttrs, controller) { ... },
- *       //  post: function postLink(scope, iElement, iAttrs, controller) { ... }
- *       // }
- *       // or
- *       // link: function postLink( ... ) { ... }
- *     };
- *     return directiveDefinitionObject;
- *   });
- * ```
- *
- * <div class="alert alert-warning">
- * **Note:** Any unspecified options will use the default value. You can see the default values below.
- * </div>
- *
- * Therefore the above can be simplified as:
- *
- * ```js
- *   var myModule = angular.module(...);
- *
- *   myModule.directive('directiveName', function factory(injectables) {
- *     var directiveDefinitionObject = {
- *       link: function postLink(scope, iElement, iAttrs) { ... }
- *     };
- *     return directiveDefinitionObject;
- *     // or
- *     // return function postLink(scope, iElement, iAttrs) { ... }
- *   });
- * ```
- *
- * ### Life-cycle hooks
- * Directive controllers can provide the following methods that are called by Angular at points in the life-cycle of the
- * directive:
- * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and
- *   had their bindings initialized (and before the pre &amp; post linking functions for the directives on
- *   this element). This is a good place to put initialization code for your controller.
- * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The
- *   `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an
- *   object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a
- *   component such as cloning the bound value to prevent accidental mutation of the outer value.
- * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on
- *   changes. Any actions that you wish to take in response to the changes that you detect must be
- *   invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook
- *   could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not
- *   be detected by Angular's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments;
- *   if detecting changes, you must store the previous value(s) for comparison to the current values.
- * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing
- *   external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in
- *   the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent
- *   components will have their `$onDestroy()` hook called before child components.
- * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link
- *   function this hook can be used to set up DOM event handlers and do direct DOM manipulation.
- *   Note that child elements that contain `templateUrl` directives will not have been compiled and linked since
- *   they are waiting for their template to load asynchronously and their own compilation and linking has been
- *   suspended until that occurs.
- *
- * #### Comparison with Angular 2 life-cycle hooks
- * Angular 2 also uses life-cycle hooks for its components. While the Angular 1 life-cycle hooks are similar there are
- * some differences that you should be aware of, especially when it comes to moving your code from Angular 1 to Angular 2:
- *
- * * Angular 1 hooks are prefixed with `$`, such as `$onInit`. Angular 2 hooks are prefixed with `ng`, such as `ngOnInit`.
- * * Angular 1 hooks can be defined on the controller prototype or added to the controller inside its constructor.
- *   In Angular 2 you can only define hooks on the prototype of the Component class.
- * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in Angular 1 than you would to
- *   `ngDoCheck` in Angular 2
- * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be
- *   propagated throughout the application.
- *   Angular 2 does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an
- *   error or do nothing depending upon the state of `enableProdMode()`.
- *
- * #### Life-cycle hook examples
- *
- * This example shows how you can check for mutations to a Date object even though the identity of the object
- * has not changed.
- *
- * <example name="doCheckDateExample" module="do-check-module">
- *   <file name="app.js">
- *     angular.module('do-check-module', [])
- *       .component('app', {
- *         template:
- *           'Month: <input ng-model="$ctrl.month" ng-change="$ctrl.updateDate()">' +
- *           'Date: {{ $ctrl.date }}' +
- *           '<test date="$ctrl.date"></test>',
- *         controller: function() {
- *           this.date = new Date();
- *           this.month = this.date.getMonth();
- *           this.updateDate = function() {
- *             this.date.setMonth(this.month);
- *           };
- *         }
- *       })
- *       .component('test', {
- *         bindings: { date: '<' },
- *         template:
- *           '<pre>{{ $ctrl.log | json }}</pre>',
- *         controller: function() {
- *           var previousValue;
- *           this.log = [];
- *           this.$doCheck = function() {
- *             var currentValue = this.date && this.date.valueOf();
- *             if (previousValue !== currentValue) {
- *               this.log.push('doCheck: date mutated: ' + this.date);
- *               previousValue = currentValue;
- *             }
- *           };
- *         }
- *       });
- *   </file>
- *   <file name="index.html">
- *     <app></app>
- *   </file>
- * </example>
- *
- * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the
- * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large
- * arrays or objects can have a negative impact on your application performance)
- *
- * <example name="doCheckArrayExample" module="do-check-module">
- *   <file name="index.html">
- *     <div ng-init="items = []">
- *       <button ng-click="items.push(items.length)">Add Item</button>
- *       <button ng-click="items = []">Reset Items</button>
- *       <pre>{{ items }}</pre>
- *       <test items="items"></test>
- *     </div>
- *   </file>
- *   <file name="app.js">
- *      angular.module('do-check-module', [])
- *        .component('test', {
- *          bindings: { items: '<' },
- *          template:
- *            '<pre>{{ $ctrl.log | json }}</pre>',
- *          controller: function() {
- *            this.log = [];
- *
- *            this.$doCheck = function() {
- *              if (this.items_ref !== this.items) {
- *                this.log.push('doCheck: items changed');
- *                this.items_ref = this.items;
- *              }
- *              if (!angular.equals(this.items_clone, this.items)) {
- *                this.log.push('doCheck: items mutated');
- *                this.items_clone = angular.copy(this.items);
- *              }
- *            };
- *          }
- *        });

- *
- * ### Directive Definition Object
- *
- * The directive definition object provides instructions to the {@link ng.$compile
- * compiler}. The attributes are:
- *
- * #### `multiElement`
- * When this property is set to true, the HTML compiler will collect DOM nodes between
- * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them
- * together as the directive elements. It is recommended that this feature be used on directives
- * which are not strictly behavioral (such as {@link ngClick}), and which
- * do not manipulate or replace child nodes (such as {@link ngInclude}).
- *
- * #### `priority`
- * When there are multiple directives defined on a single DOM element, sometimes it
- * is necessary to specify the order in which the directives are applied. The `priority` is used
- * to sort the directives before their `compile` functions get called. Priority is defined as a
- * number. Directives with greater numerical `priority` are compiled first. Pre-link functions
- * are also run in priority order, but post-link functions are run in reverse order. The order
- * of directives with the same priority is undefined. The default priority is `0`.
- *
- * #### `terminal`
- * If set to true then the current `priority` will be the last set of directives
- * which will execute (any directives at the current priority will still execute
- * as the order of execution on same `priority` is undefined). Note that expressions
- * and other directives used in the directive's template will also be excluded from execution.
- *
- * #### `scope`
- * The scope property can be `true`, an object or a falsy value:
- *
- * * **falsy:** No scope will be created for the directive. The directive will use its parent's scope.
- *
- * * **`true`:** A new child scope that prototypically inherits from its parent will be created for
- * the directive's element. If multiple directives on the same element request a new scope,
- * only one new scope is created. The new scope rule does not apply for the root of the template
- * since the root of the template always gets a new scope.
- *
- * * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's element. The
- * 'isolate' scope differs from normal scope in that it does not prototypically inherit from its parent
- * scope. This is useful when creating reusable components, which should not accidentally read or modify
- * data in the parent scope.
- *
- * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the
- * directive's element. These local properties are useful for aliasing values for templates. The keys in
- * the object hash map to the name of the property on the isolate scope; the values define how the property
- * is bound to the parent scope, via matching attributes on the directive's element:
- *
- * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
- *   always a string since DOM attributes are strings. If no `attr` name is specified then the
- *   attribute name is assumed to be the same as the local name. Given `<my-component
- *   my-attr="hello {{name}}">` and the isolate scope definition `scope: { localName:'@myAttr' }`,
- *   the directive's scope property `localName` will reflect the interpolated value of `hello
- *   {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's
- *   scope. The `name` is read from the parent scope (not the directive's scope).
- *
- * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression
- *   passed via the attribute `attr`. The expression is evaluated in the context of the parent scope.
- *   If no `attr` name is specified then the attribute name is assumed to be the same as the local
- *   name. Given `<my-component my-attr="parentModel">` and the isolate scope definition `scope: {
- *   localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the
- *   value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in
- *   `localModel` and vice versa. Optional attributes should be marked as such with a question mark:
- *   `=?` or `=?attr`. If the binding expression is non-assignable, or if the attribute isn't
- *   optional and doesn't exist, an exception ({@link error/$compile/nonassign `$compile:nonassign`})
- *   will be thrown upon discovering changes to the local value, since it will be impossible to sync
- *   them back to the parent scope. By default, the {@link ng.$rootScope.Scope#$watch `$watch`}
- *   method is used for tracking changes, and the equality check is based on object identity.
- *   However, if an object literal or an array literal is passed as the binding expression, the
- *   equality check is done by value (using the {@link angular.equals} function). It's also possible
- *   to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection
- *   `$watchCollection`}: use `=*` or `=*attr` (`=*?` or `=*?attr` if the attribute is optional).
- *
-  * * `<` or `<attr` - set up a one-way (one-directional) binding between a local scope property and an
- *   expression passed via the attribute `attr`. The expression is evaluated in the context of the
- *   parent scope. If no `attr` name is specified then the attribute name is assumed to be the same as the
- *   local name. You can also make the binding optional by adding `?`: `<?` or `<?attr`.
- *
- *   For example, given `<my-component my-attr="parentModel">` and directive definition of
- *   `scope: { localModel:'<myAttr' }`, then the isolated scope property `localModel` will reflect the
- *   value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected
- *   in `localModel`, but changes in `localModel` will not reflect in `parentModel`. There are however
- *   two caveats:
- *     1. one-way binding does not copy the value from the parent to the isolate scope, it simply
- *     sets the same value. That means if your bound value is an object, changes to its properties
- *     in the isolated scope will be reflected in the parent scope (because both reference the same object).
- *     2. one-way binding watches changes to the **identity** of the parent value. That means the
- *     {@link ng.$rootScope.Scope#$watch `$watch`} on the parent value only fires if the reference
- *     to the value has changed. In most cases, this should not be of concern, but can be important
- *     to know if you one-way bind to an object, and then replace that object in the isolated scope.
- *     If you now change a property of the object in your parent scope, the change will not be
- *     propagated to the isolated scope, because the identity of the object on the parent scope
- *     has not changed. Instead you must assign a new object.
- *
- *   One-way binding is useful if you do not plan to propagate changes to your isolated scope bindings
- *   back to the parent. However, it does not make this completely impossible.
- *
- * * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope. If
- *   no `attr` name is specified then the attribute name is assumed to be the same as the local name.
- *   Given `<my-component my-attr="count = count + value">` and the isolate scope definition `scope: {
- *   localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for
- *   the `count = count + value` expression. Often it's desirable to pass data from the isolated scope
- *   via an expression to the parent scope. This can be done by passing a map of local variable names
- *   and values into the expression wrapper fn. For example, if the expression is `increment(amount)`
- *   then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`.
- *
- * In general it's possible to apply more than one directive to one element, but there might be limitations
- * depending on the type of scope required by the directives. The following points will help explain these limitations.
- * For simplicity only two directives are taken into account, but it is also applicable for several directives:
- *
- * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope
- * * **child scope** + **no scope** =>  Both directives will share one single child scope
- * * **child scope** + **child scope** =>  Both directives will share one single child scope
- * * **isolated scope** + **no scope** =>  The isolated directive will use it's own created isolated scope. The other directive will use
- * its parent's scope
- * * **isolated scope** + **child scope** =>  **Won't work!** Only one scope can be related to one element. Therefore these directives cannot
- * be applied to the same element.
- * * **isolated scope** + **isolated scope**  =>  **Won't work!** Only one scope can be related to one element. Therefore these directives
- * cannot be applied to the same element.
- *
- *
- * #### `bindToController`
- * This property is used to bind scope properties directly to the controller. It can be either
- * `true` or an object hash with the same format as the `scope` property. Additionally, a controller
- * alias must be set, either by using `controllerAs: 'myAlias'` or by specifying the alias in the controller
- * definition: `controller: 'myCtrl as myAlias'`.
- *
- * When an isolate scope is used for a directive (see above), `bindToController: true` will
- * allow a component to have its properties bound to the controller, rather than to scope.
- *
- * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller
- * properties. You can access these bindings once they have been initialized by providing a controller method called
- * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings
- * initialized.
- *
- * <div class="alert alert-warning">
- * **Deprecation warning:** although bindings for non-ES6 class controllers are currently
- * bound to `this` before the controller constructor is called, this use is now deprecated. Please place initialization
- * code that relies upon bindings inside a `$onInit` method on the controller, instead.
- * </div>
- *
- * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property.
- * This will set up the scope bindings to the controller directly. Note that `scope` can still be used
- * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate
- * scope (useful for component directives).
- *
- * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`.
- *
- *
- * #### `controller`
- * Controller constructor function. The controller is instantiated before the
- * pre-linking phase and can be accessed by other directives (see
- * `require` attribute). This allows the directives to communicate with each other and augment
- * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
- *
- * * `$scope` - Current scope associated with the element
- * * `$element` - Current element
- * * `$attrs` - Current attributes object for the element
- * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:
- *   `function([scope], cloneLinkingFn, futureParentElement, slotName)`:
- *    * `scope`: (optional) override the scope.
- *    * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content.
- *    * `futureParentElement` (optional):
- *        * defines the parent to which the `cloneLinkingFn` will add the cloned elements.
- *        * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.
- *        * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)
- *          and when the `cloneLinkinFn` is passed,
- *          as those elements need to created and cloned in a special way when they are defined outside their
- *          usual containers (e.g. like `<svg>`).
- *        * See also the `directive.templateNamespace` property.
- *    * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`)
- *      then the default translusion is provided.
- *    The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns
- *    `true` if the specified slot contains content (i.e. one or more DOM nodes).
- *
- * #### `require`
- * Require another directive and inject its controller as the fourth argument to the linking function. The
- * `require` property can be a string, an array or an object:
- * * a **string** containing the name of the directive to pass to the linking function
- * * an **array** containing the names of directives to pass to the linking function. The argument passed to the
- * linking function will be an array of controllers in the same order as the names in the `require` property
- * * an **object** whose property values are the names of the directives to pass to the linking function. The argument
- * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding
- * controllers.
- *
- * If the `require` property is an object and `bindToController` is truthy, then the required controllers are
- * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers
- * have been constructed but before `$onInit` is called.
- * If the name of the required controller is the same as the local name (the key), the name can be
- * omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`.
- * See the {@link $compileProvider#component} helper for an example of how this can be used.
- * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is
- * raised (unless no link function is specified and the required controllers are not being bound to the directive
- * controller, in which case error checking is skipped). The name can be prefixed with:
- *
- * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
- * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
- * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.
- * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.
- * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass
- *   `null` to the `link` fn if not found.
- * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass
- *   `null` to the `link` fn if not found.
- *
- *
- * #### `controllerAs`
- * Identifier name for a reference to the controller in the directive's scope.
- * This allows the controller to be referenced from the directive template. This is especially
- * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible
- * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the
- * `controllerAs` reference might overwrite a property that already exists on the parent scope.
- *
- *
- * #### `restrict`
- * String of subset of `EACM` which restricts the directive to a specific directive
- * declaration style. If omitted, the defaults (elements and attributes) are used.
- *
- * * `E` - Element name (default): `<my-directive></my-directive>`
- * * `A` - Attribute (default): `<div my-directive="exp"></div>`
- * * `C` - Class: `<div class="my-directive: exp;"></div>`
- * * `M` - Comment: `<!-- directive: my-directive exp -->`
- *
- *
- * #### `templateNamespace`
- * String representing the document type used by the markup in the template.
- * AngularJS needs this information as those elements need to be created and cloned
- * in a special way when they are defined outside their usual containers like `<svg>` and `<math>`.
- *
- * * `html` - All root nodes in the template are HTML. Root nodes may also be
- *   top-level elements such as `<svg>` or `<math>`.
- * * `svg` - The root nodes in the template are SVG elements (excluding `<math>`).
- * * `math` - The root nodes in the template are MathML elements (excluding `<svg>`).
- *
- * If no `templateNamespace` is specified, then the namespace is considered to be `html`.
- *
- * #### `template`
- * HTML markup that may:
- * * Replace the contents of the directive's element (default).
- * * Replace the directive's element itself (if `replace` is true - DEPRECATED).
- * * Wrap the contents of the directive's element (if `transclude` is true).
- *
- * Value may be:
- *
- * * A string. For example `<div red-on-hover>{{delete_str}}</div>`.
- * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`
- *   function api below) and returns a string value.
- *
- *
- * #### `templateUrl`
- * This is similar to `template` but the template is loaded from the specified URL, asynchronously.
- *
- * Because template loading is asynchronous the compiler will suspend compilation of directives on that element
- * for later when the template has been resolved.  In the meantime it will continue to compile and link
- * sibling and parent elements as though this element had not contained any directives.
- *
- * The compiler does not suspend the entire compilation to wait for templates to be loaded because this
- * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the
- * case when only one deeply nested directive has `templateUrl`.
- *
- * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}
- *
- * You can specify `templateUrl` as a string representing the URL or as a function which takes two
- * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
- * a string value representing the url.  In either case, the template URL is passed through {@link
- * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.
- *
- *
- * #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0)
- * specify what the template should replace. Defaults to `false`.
- *
- * * `true` - the template will replace the directive's element.
- * * `false` - the template will replace the contents of the directive's element.
- *
- * The replacement process migrates all of the attributes / classes from the old element to the new
- * one. See the {@link guide/directive#template-expanding-directive
- * Directives Guide} for an example.
- *
- * There are very few scenarios where element replacement is required for the application function,
- * the main one being reusable custom components that are used within SVG contexts
- * (because SVG doesn't work with custom elements in the DOM tree).
- *
- * #### `transclude`
- * Extract the contents of the element where the directive appears and make it available to the directive.
- * The contents are compiled and provided to the directive as a **transclusion function**. See the
- * {@link $compile#transclusion Transclusion} section below.
- *
- *
- * #### `compile`
- *
- * ```js
- *   function compile(tElement, tAttrs, transclude) { ... }
- * ```
- *
- * The compile function deals with transforming the template DOM. Since most directives do not do
- * template transformation, it is not used often. The compile function takes the following arguments:
- *
- *   * `tElement` - template element - The element where the directive has been declared. It is
- *     safe to do template transformation on the element and child elements only.
- *
- *   * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
- *     between all directive compile functions.
- *
- *   * `transclude` -  [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`
- *
- * <div class="alert alert-warning">
- * **Note:** The template instance and the link instance may be different objects if the template has
- * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
- * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
- * should be done in a linking function rather than in a compile function.
- * </div>
-
- * <div class="alert alert-warning">
- * **Note:** The compile function cannot handle directives that recursively use themselves in their
- * own templates or compile functions. Compiling these directives results in an infinite loop and
- * stack overflow errors.
- *
- * This can be avoided by manually using $compile in the postLink function to imperatively compile
- * a directive's template instead of relying on automatic template compilation via `template` or
- * `templateUrl` declaration or manual compilation inside the compile function.
- * </div>
- *
- * <div class="alert alert-danger">
- * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it
- *   e.g. does not know about the right outer scope. Please use the transclude function that is passed
- *   to the link function instead.
- * </div>
-
- * A compile function can have a return value which can be either a function or an object.
- *
- * * returning a (post-link) function - is equivalent to registering the linking function via the
- *   `link` property of the config object when the compile function is empty.
- *
- * * returning an object with function(s) registered via `pre` and `post` properties - allows you to
- *   control when a linking function should be called during the linking phase. See info about
- *   pre-linking and post-linking functions below.
- *
- *
- * #### `link`
- * This property is used only if the `compile` property is not defined.
- *
- * ```js
- *   function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
- * ```
- *
- * The link function is responsible for registering DOM listeners as well as updating the DOM. It is
- * executed after the template has been cloned. This is where most of the directive logic will be
- * put.
- *
- *   * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the
- *     directive for registering {@link ng.$rootScope.Scope#$watch watches}.
- *
- *   * `iElement` - instance element - The element where the directive is to be used. It is safe to
- *     manipulate the children of the element only in `postLink` function since the children have
- *     already been linked.
- *
- *   * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
- *     between all directive linking functions.
- *
- *   * `controller` - the directive's required controller instance(s) - Instances are shared
- *     among all directives, which allows the directives to use the controllers as a communication
- *     channel. The exact value depends on the directive's `require` property:
- *       * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one
- *       * `string`: the controller instance
- *       * `array`: array of controller instances
- *
- *     If a required controller cannot be found, and it is optional, the instance is `null`,
- *     otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.
- *
- *     Note that you can also require the directive's own controller - it will be made available like
- *     any other controller.
- *
- *   * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
- *     This is the same as the `$transclude` parameter of directive controllers,
- *     see {@link ng.$compile#-controller- the controller section for details}.
- *     `function([scope], cloneLinkingFn, futureParentElement)`.
- *
- * #### Pre-linking function
- *
- * Executed before the child elements are linked. Not safe to do DOM transformation since the
- * compiler linking function will fail to locate the correct elements for linking.
- *
- * #### Post-linking function
- *
- * Executed after the child elements are linked.
- *
- * Note that child elements that contain `templateUrl` directives will not have been compiled
- * and linked since they are waiting for their template to load asynchronously and their own
- * compilation and linking has been suspended until that occurs.
- *
- * It is safe to do DOM transformation in the post-linking function on elements that are not waiting
- * for their async templates to be resolved.
- *
- *
- * ### Transclusion
- *
- * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and
- * copying them to another part of the DOM, while maintaining their connection to the original AngularJS
- * scope from where they were taken.
- *
- * Transclusion is used (often with {@link ngTransclude}) to insert the
- * original contents of a directive's element into a specified place in the template of the directive.
- * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded
- * content has access to the properties on the scope from which it was taken, even if the directive
- * has isolated scope.
- * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.
- *
- * This makes it possible for the widget to have private state for its template, while the transcluded
- * content has access to its originating scope.
- *
- * <div class="alert alert-warning">
- * **Note:** When testing an element transclude directive you must not place the directive at the root of the
- * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives
- * Testing Transclusion Directives}.
- * </div>
- *
- * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the
- * directive's element, the entire element or multiple parts of the element contents:
- *
- * * `true` - transclude the content (i.e. the child nodes) of the directive's element.
- * * `'element'` - transclude the whole of the directive's element including any directives on this
- *   element that defined at a lower priority than this directive. When used, the `template`
- *   property is ignored.
- * * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template.
- *
- * **Mult-slot transclusion** is declared by providing an object for the `transclude` property.
- *
- * This object is a map where the keys are the name of the slot to fill and the value is an element selector
- * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`)
- * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc).
- *
- * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives}
- *
- * If the element selector is prefixed with a `?` then that slot is optional.
- *
- * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `<my-custom-element>` elements to
- * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive.
- *
- * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements
- * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call
- * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and
- * injectable into the directive's controller.
- *
- *
- * #### Transclusion Functions
- *
- * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion
- * function** to the directive's `link` function and `controller`. This transclusion function is a special
- * **linking function** that will return the compiled contents linked to a new transclusion scope.
- *
- * <div class="alert alert-info">
- * If you are just using {@link ngTransclude} then you don't need to worry about this function, since
- * ngTransclude will deal with it for us.
- * </div>
- *
- * If you want to manually control the insertion and removal of the transcluded content in your directive
- * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery
- * object that contains the compiled DOM, which is linked to the correct transclusion scope.
- *
- * When you call a transclusion function you can pass in a **clone attach function**. This function accepts
- * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded
- * content and the `scope` is the newly created transclusion scope, to which the clone is bound.
- *
- * <div class="alert alert-info">
- * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function
- * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.
- * </div>
- *
- * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone
- * attach function**:
- *
- * ```js
- * var transcludedContent, transclusionScope;
- *
- * $transclude(function(clone, scope) {
- *   element.append(clone);
- *   transcludedContent = clone;
- *   transclusionScope = scope;
- * });
- * ```
- *
- * Later, if you want to remove the transcluded content from your DOM then you should also destroy the
- * associated transclusion scope:
- *
- * ```js
- * transcludedContent.remove();
- * transclusionScope.$destroy();
- * ```
- *
- * <div class="alert alert-info">
- * **Best Practice**: if you intend to add and remove transcluded content manually in your directive
- * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),
- * then you are also responsible for calling `$destroy` on the transclusion scope.
- * </div>
- *
- * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}
- * automatically destroy their transcluded clones as necessary so you do not need to worry about this if
- * you are simply using {@link ngTransclude} to inject the transclusion into your directive.
- *
- *
- * #### Transclusion Scopes
- *
- * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion
- * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed
- * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it
- * was taken.
- *
- * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look
- * like this:
- *
- * ```html
- * <div ng-app>
- *   <div isolate>
- *     <div transclusion>
- *     </div>
- *   </div>
- * </div>
- * ```
- *
- * The `$parent` scope hierarchy will look like this:
- *
-   ```
-   - $rootScope
-     - isolate
-       - transclusion
-   ```
- *
- * but the scopes will inherit prototypically from different scopes to their `$parent`.
- *
-   ```
-   - $rootScope
-     - transclusion
-   - isolate
-   ```
- *
- *
- * ### Attributes
- *
- * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
- * `link()` or `compile()` functions. It has a variety of uses.
- *
- * * *Accessing normalized attribute names:* Directives like 'ngBind' can be expressed in many ways:
- *   'ng:bind', `data-ng-bind`, or 'x-ng-bind'. The attributes object allows for normalized access
- *   to the attributes.
- *
- * * *Directive inter-communication:* All directives share the same instance of the attributes
- *   object which allows the directives to use the attributes object as inter directive
- *   communication.
- *
- * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
- *   allowing other directives to read the interpolated value.
- *
- * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
- *   that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
- *   the only way to easily get the actual value because during the linking phase the interpolation
- *   hasn't been evaluated yet and so the value is at this time set to `undefined`.
- *
- * ```js
- * function linkingFn(scope, elm, attrs, ctrl) {
- *   // get the attribute value
- *   console.log(attrs.ngModel);
- *
- *   // change the attribute
- *   attrs.$set('ngModel', 'new value');
- *
- *   // observe changes to interpolated attribute
- *   attrs.$observe('ngModel', function(value) {
- *     console.log('ngModel has changed value to ' + value);
- *   });
- * }
- * ```
- *
- * ## Example
- *
- * <div class="alert alert-warning">
- * **Note**: Typically directives are registered with `module.directive`. The example below is
- * to illustrate how `$compile` works.
- * </div>
- *
- <example module="compileExample">
-   <file name="index.html">
-    <script>
-      angular.module('compileExample', [], function($compileProvider) {
-        // configure new 'compile' directive by passing a directive
-        // factory function. The factory function injects the '$compile'
-        $compileProvider.directive('compile', function($compile) {
-          // directive factory creates a link function
-          return function(scope, element, attrs) {
-            scope.$watch(
-              function(scope) {
-                 // watch the 'compile' expression for changes
-                return scope.$eval(attrs.compile);
-              },
-              function(value) {
-                // when the 'compile' expression changes
-                // assign it into the current DOM
-                element.html(value);
-
-                // compile the new DOM and link it to the current
-                // scope.
-                // NOTE: we only compile .childNodes so that
-                // we don't get into infinite loop compiling ourselves
-                $compile(element.contents())(scope);
-              }
-            );
-          };
-        });
-      })
-      .controller('GreeterController', ['$scope', function($scope) {
-        $scope.name = 'Angular';
-        $scope.html = 'Hello {{name}}';
-      }]);
-    </script>
-    <div ng-controller="GreeterController">
-      <input ng-model="name"> <br/>
-      <textarea ng-model="html"></textarea> <br/>
-      <div compile="html"></div>
-    </div>
-   </file>
-   <file name="protractor.js" type="protractor">

-       var output = $('div[compile]');
-       // The initial state reads 'Hello Angular'.
-       expect(output.getText()).toBe('Hello Angular');
-       textarea.clear();
-       textarea.sendKeys('{{name}}!');

- * **Note:** Passing a `transclude` function to the $compile function is deprecated, as it
- *   e.g. will not use the right outer scope. Please pass the transclude function as a

- * @param {number} maxPriority only apply directives lower than given priority (Only effects the
- *                 root element(s), not their children)
- * @returns {function(scope, cloneAttachFn=, options=)} a link function which is used to bind template
- * (a DOM element/tree) to a scope. Where:
- *
- *  * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
- *  * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
- *  `template` and call the `cloneAttachFn` function allowing the caller to attach the
- *  cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
- *  called as: <br/> `cloneAttachFn(clonedElement, scope)` where:
- *
- *      * `clonedElement` - is a clone of the original `element` passed into the compiler.
- *      * `scope` - is the current scope with which the linking function is working with.
- *
- *  * `options` - An optional object hash with linking options. If `options` is provided, then the following
- *  keys may be used to control linking behavior:
- *
- *      * `parentBoundTranscludeFn` - the transclude function made available to
- *        directives; if given, it will be passed through to the link functions of
- *        directives found in `element` during compilation.
- *      * `transcludeControllers` - an object hash with keys that map controller names
- *        to a hash with the key `instance`, which maps to the controller instance;
- *        if given, it will make the controllers available to directives on the compileNode:
- *        ```
- *        {
- *          parent: {
- *            instance: parentControllerInstance
- *          }
- *        }
- *        ```
- *      * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add
- *        the cloned elements; only needed for transcludes that are allowed to contain non html
- *        elements (e.g. SVG elements). See also the directive.controller property.
- *
- * Calling the linking function returns the element of the template. It is either the original
- * element passed in, or the clone of the element if the `cloneAttachFn` is provided.
- *
- * After linking the view is not updated until after a call to $digest which typically is done by
- * Angular automatically.
- *
- * If you need access to the bound view, there are two ways to do it:
- *
- * - If you are not asking the linking function to clone the template, create the DOM element(s)
- *   before you send them to the compiler and keep this reference around.
- *   ```js
- *     var element = $compile('<p>{{total}}</p>')(scope);
- *   ```
- *
- * - if on the other hand, you need the element to be cloned, the view reference from the original
- *   example would not point to the clone, but rather to the original template that was cloned. In
- *   this case, you can access the clone via the cloneAttachFn:
- *   ```js
- *     var templateElement = angular.element('<p>{{total}}</p>'),
- *         scope = ....;
- *
- *     var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
- *       //attach the clone to DOM document at the right place
- *     });
- *
- *     //now we have reference to the cloned DOM via `clonedElement`
- *   ```
- *
- *

- * {@link guide/compiler Angular HTML Compiler} section of the Developer Guide.

-   * @description
-   * Register a **component definition** with the compiler. This is a shorthand for registering a special
-   * type of directive, which represents a self-contained UI component in your application. Such components
-   * are always isolated (i.e. `scope: {}`) and are always restricted to elements (i.e. `restrict: 'E'`).
-   *
-   * Component definitions are very simple and do not require as much configuration as defining general
-   * directives. Component definitions usually consist only of a template and a controller backing it.
-   *
-   * In order to make the definition easier, components enforce best practices like use of `controllerAs`,
-   * `bindToController`. They always have **isolate scope** and are restricted to elements.
-   *
-   * Here are a few examples of how you would usually define components:
-   *
-   * ```js
-   *   var myMod = angular.module(...);
-   *   myMod.component('myComp', {
-   *     template: '<div>My name is {{$ctrl.name}}</div>',
-   *     controller: function() {
-   *       this.name = 'shahar';
-   *     }
-   *   });
-   *
-   *   myMod.component('myComp', {
-   *     template: '<div>My name is {{$ctrl.name}}</div>',
-   *     bindings: {name: '@'}
-   *   });
-   *
-   *   myMod.component('myComp', {
-   *     templateUrl: 'views/my-comp.html',
-   *     controller: 'MyCtrl',
-   *     controllerAs: 'ctrl',
-   *     bindings: {name: '@'}
-   *   });
-   *
-   * ```
-   * For more examples, and an in-depth guide, see the {@link guide/component component guide}.

- * @ngdoc service
- * @name $exceptionHandler
- * @requires ng.$log
- *
- * @description
- * Any uncaught exception in angular expressions is delegated to this service.
- * The default implementation simply delegates to `$log.error` which logs it into
- * the browser console.
- *
- * In unit tests, if `angular-mocks.js` is loaded, this service is overridden by
- * {@link ngMock.$exceptionHandler mock $exceptionHandler} which aids in testing.
- *
- * ## Example:
- *
- * The example below will overwrite the default `$exceptionHandler` in order to (a) log uncaught
- * errors to the backend for later inspection by the developers and (b) to use `$log.warn()` instead
- * of `$log.error()`.
- *
- * ```js
- *   angular.
- *     module('exceptionOverwrite', []).
- *     factory('$exceptionHandler', ['$log', 'logErrorsToBackend', function($log, logErrorsToBackend) {
- *       return function myExceptionHandler(exception, cause) {
- *         logErrorsToBackend(exception, cause);
- *         $log.warn(exception, cause);
- *       };
- *     }]);
- * ```
- *
- * <hr />
- * Note, that code executed in event-listeners (even those registered using jqLite's `on`/`bind`
- * methods) does not delegate exceptions to the {@link ng.$exceptionHandler $exceptionHandler}
- * (unless executed during a digest).
- *
- * If you wish, you can manually delegate exceptions, e.g.
- * `try { ... } catch(e) { $exceptionHandler(e); }`
- *
- * @param {Error} exception Exception associated with the error.
- * @param {string=} cause Optional information about the context in which

-     * @description
-     * The `$http` service is a core Angular service that facilitates communication with the remote
-     * HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest)
-     * object or via [JSONP](http://en.wikipedia.org/wiki/JSONP).
-     *
-     * For unit testing applications that use `$http` service, see
-     * {@link ngMock.$httpBackend $httpBackend mock}.
-     *
-     * For a higher level of abstraction, please check out the {@link ngResource.$resource
-     * $resource} service.
-     *
-     * The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
-     * the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
-     * it is important to familiarize yourself with these APIs and the guarantees they provide.
-     *
-     *
-     * ## General usage
-     * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} —
-     * that is used to generate an HTTP request and returns  a {@link ng.$q promise}.
-     *
-     * ```js
-     *   // Simple GET request example:
-     *   $http({
-     *     method: 'GET',
-     *     url: '/someUrl'
-     *   }).then(function successCallback(response) {
-     *       // this callback will be called asynchronously
-     *       // when the response is available
-     *     }, function errorCallback(response) {
-     *       // called asynchronously if an error occurs
-     *       // or server returns response with an error status.
-     *     });
-     * ```
-     *
-     * The response object has these properties:
-     *
-     *   - **data** – `{string|Object}` – The response body transformed with the transform
-     *     functions.
-     *   - **status** – `{number}` – HTTP status code of the response.
-     *   - **headers** – `{function([headerName])}` – Header getter function.
-     *   - **config** – `{Object}` – The configuration object that was used to generate the request.
-     *   - **statusText** – `{string}` – HTTP status text of the response.
-     *
-     * A response status code between 200 and 299 is considered a success status and will result in
-     * the success callback being called. Any response status code outside of that range is
-     * considered an error status and will result in the error callback being called.
-     * Also, status codes less than -1 are normalized to zero. -1 usually means the request was
-     * aborted, e.g. using a `config.timeout`.
-     * Note that if the response is a redirect, XMLHttpRequest will transparently follow it, meaning
-     * that the outcome (success or error) will be determined by the final response status code.
-     *
-     *
-     * ## Shortcut methods
-     *
-     * Shortcut methods are also available. All shortcut methods require passing in the URL, and
-     * request data must be passed in for POST/PUT requests. An optional config can be passed as the
-     * last argument.
-     *
-     * ```js
-     *   $http.get('/someUrl', config).then(successCallback, errorCallback);
-     *   $http.post('/someUrl', data, config).then(successCallback, errorCallback);
-     * ```
-     *
-     * Complete list of shortcut methods:
-     *
-     * - {@link ng.$http#get $http.get}
-     * - {@link ng.$http#head $http.head}
-     * - {@link ng.$http#post $http.post}
-     * - {@link ng.$http#put $http.put}
-     * - {@link ng.$http#delete $http.delete}
-     * - {@link ng.$http#jsonp $http.jsonp}
-     * - {@link ng.$http#patch $http.patch}
-     *
-     *
-     * ## Writing Unit Tests that use $http
-     * When unit testing (using {@link ngMock ngMock}), it is necessary to call
-     * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending
-     * request using trained responses.
-     *
-     * ```
-     * $httpBackend.expectGET(...);
-     * $http.get(...);
-     * $httpBackend.flush();
-     * ```
-     *
-     * ## Deprecation Notice
-     * <div class="alert alert-danger">
-     *   The `$http` legacy promise methods `success` and `error` have been deprecated.
-     *   Use the standard `then` method instead.
-     *   If {@link $httpProvider#useLegacyPromiseExtensions `$httpProvider.useLegacyPromiseExtensions`} is set to
-     *   `false` then these methods will throw {@link $http:legacy `$http/legacy`} error.
-     * </div>
-     *
-     * ## Setting HTTP Headers
-     *
-     * The $http service will automatically add certain HTTP headers to all requests. These defaults
-     * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
-     * object, which currently contains this default configuration:
-     *
-     * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
-     *   - `Accept: application/json, text/plain, * / *`
-     * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
-     *   - `Content-Type: application/json`
-     * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
-     *   - `Content-Type: application/json`
-     *
-     * To add or overwrite these defaults, simply add or remove a property from these configuration
-     * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
-     * with the lowercased HTTP method name as the key, e.g.
-     * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.
-     *
-     * The defaults can also be set at runtime via the `$http.defaults` object in the same
-     * fashion. For example:
-     *
-     * ```
-     * module.run(function($http) {
-     *   $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w';
-     * });
-     * ```
-     *
-     * In addition, you can supply a `headers` property in the config object passed when
-     * calling `$http(config)`, which overrides the defaults without changing them globally.
-     *
-     * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,
-     * Use the `headers` property, setting the desired header to `undefined`. For example:
-     *
-     * ```js
-     * var req = {
-     *  method: 'POST',
-     *  url: 'http://example.com',
-     *  headers: {
-     *    'Content-Type': undefined
-     *  },
-     *  data: { test: 'test' }
-     * }
-     *
-     * $http(req).then(function(){...}, function(){...});
-     * ```
-     *
-     * ## Transforming Requests and Responses
-     *
-     * Both requests and responses can be transformed using transformation functions: `transformRequest`
-     * and `transformResponse`. These properties can be a single function that returns
-     * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,
-     * which allows you to `push` or `unshift` a new transformation function into the transformation chain.
-     *
-     * <div class="alert alert-warning">
-     * **Note:** Angular does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline.
-     * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference).
-     * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest
-     * function will be reflected on the scope and in any templates where the object is data-bound.
-     * To prevent this, transform functions should have no side-effects.
-     * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return.
-     * </div>
-     *
-     * ### Default Transformations
-     *
-     * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and
-     * `defaults.transformResponse` properties. If a request does not provide its own transformations
-     * then these will be applied.
-     *
-     * You can augment or replace the default transformations by modifying these properties by adding to or
-     * replacing the array.
-     *
-     * Angular provides the following default transformations:
-     *
-     * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`):
-     *
-     * - If the `data` property of the request configuration object contains an object, serialize it
-     *   into JSON format.
-     *
-     * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`):
-     *
-     *  - If XSRF prefix is detected, strip it (see Security Considerations section below).
-     *  - If JSON response is detected, deserialize it using a JSON parser.
-     *
-     *
-     * ### Overriding the Default Transformations Per Request
-     *
-     * If you wish to override the request/response transformations only for a single request then provide
-     * `transformRequest` and/or `transformResponse` properties on the configuration object passed
-     * into `$http`.
-     *
-     * Note that if you provide these properties on the config object the default transformations will be
-     * overwritten. If you wish to augment the default transformations then you must include them in your
-     * local transformation array.
-     *
-     * The following code demonstrates adding a new response transformation to be run after the default response
-     * transformations have been run.
-     *
-     * ```js
-     * function appendTransform(defaults, transform) {
-     *
-     *   // We can't guarantee that the default transformation is an array
-     *   defaults = angular.isArray(defaults) ? defaults : [defaults];
-     *
-     *   // Append the new transformation to the defaults
-     *   return defaults.concat(transform);
-     * }
-     *
-     * $http({
-     *   url: '...',
-     *   method: 'GET',
-     *   transformResponse: appendTransform($http.defaults.transformResponse, function(value) {
-     *     return doTransform(value);
-     *   })
-     * });
-     * ```
-     *
-     *
-     * ## Caching
-     *
-     * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must
-     * set the config.cache value or the default cache value to TRUE or to a cache object (created
-     * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes
-     * precedence over the default cache value.
-     *
-     * In order to:
-     *   * cache all responses - set the default cache value to TRUE or to a cache object
-     *   * cache a specific response - set config.cache value to TRUE or to a cache object
-     *
-     * If caching is enabled, but neither the default cache nor config.cache are set to a cache object,
-     * then the default `$cacheFactory("$http")` object is used.
-     *
-     * The default cache value can be set by updating the
-     * {@link ng.$http#defaults `$http.defaults.cache`} property or the
-     * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property.
-     *
-     * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using
-     * the relevant cache object. The next time the same request is made, the response is returned
-     * from the cache without sending a request to the server.
-     *
-     * Take note that:
-     *
-     *   * Only GET and JSONP requests are cached.
-     *   * The cache key is the request URL including search parameters; headers are not considered.
-     *   * Cached responses are returned asynchronously, in the same way as responses from the server.
-     *   * If multiple identical requests are made using the same cache, which is not yet populated,
-     *     one request will be made to the server and remaining requests will return the same response.
-     *   * A cache-control header on the response does not affect if or how responses are cached.
-     *
-     *
-     * ## Interceptors
-     *
-     * Before you start creating interceptors, be sure to understand the
-     * {@link ng.$q $q and deferred/promise APIs}.
-     *
-     * For purposes of global error handling, authentication, or any kind of synchronous or
-     * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
-     * able to intercept requests before they are handed to the server and
-     * responses before they are handed over to the application code that
-     * initiated these requests. The interceptors leverage the {@link ng.$q
-     * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
-     *
-     * The interceptors are service factories that are registered with the `$httpProvider` by
-     * adding them to the `$httpProvider.interceptors` array. The factory is called and
-     * injected with dependencies (if specified) and returns the interceptor.
-     *
-     * There are two kinds of interceptors (and two kinds of rejection interceptors):
-     *
-     *   * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to
-     *     modify the `config` object or create a new one. The function needs to return the `config`
-     *     object directly, or a promise containing the `config` or a new `config` object.
-     *   * `requestError`: interceptor gets called when a previous interceptor threw an error or
-     *     resolved with a rejection.
-     *   * `response`: interceptors get called with http `response` object. The function is free to
-     *     modify the `response` object or create a new one. The function needs to return the `response`
-     *     object directly, or as a promise containing the `response` or a new `response` object.
-     *   * `responseError`: interceptor gets called when a previous interceptor threw an error or
-     *     resolved with a rejection.
-     *
-     *
-     * ```js
-     *   // register the interceptor as a service
-     *   $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
-     *     return {
-     *       // optional method
-     *       'request': function(config) {
-     *         // do something on success
-     *         return config;
-     *       },
-     *
-     *       // optional method
-     *      'requestError': function(rejection) {
-     *         // do something on error
-     *         if (canRecover(rejection)) {
-     *           return responseOrNewPromise
-     *         }
-     *         return $q.reject(rejection);
-     *       },
-     *
-     *
-     *
-     *       // optional method
-     *       'response': function(response) {
-     *         // do something on success
-     *         return response;
-     *       },
-     *
-     *       // optional method
-     *      'responseError': function(rejection) {
-     *         // do something on error
-     *         if (canRecover(rejection)) {
-     *           return responseOrNewPromise
-     *         }
-     *         return $q.reject(rejection);
-     *       }
-     *     };
-     *   });
-     *

-     * ## Security Considerations
-     *
-     * When designing web applications, consider security threats from:
-     *
-     * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
-     * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
-     *
-     * Both server and the client must cooperate in order to eliminate these threats. Angular comes
-     * pre-configured with strategies that address these issues, but for this to work backend server
-     * cooperation is required.
-     *
-     * ### JSON Vulnerability Protection
-     *
-     * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
-     * allows third party website to turn your JSON resource URL into
-     * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To
-     * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
-     * Angular will automatically strip the prefix before processing it as JSON.
-     *
-     * For example if your server needs to return:
-     * ```js
-     * ['one','two']
-     * ```
-     *
-     * which is vulnerable to attack, your server can return:
-     * ```js
-     * )]}',
-     * ['one','two']
-     * ```
-     *
-     * Angular will strip the prefix, before processing the JSON.
-     *
-     *
-     * ### Cross Site Request Forgery (XSRF) Protection
-     *
-     * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by
-     * which the attacker can trick an authenticated user into unknowingly executing actions on your
-     * website. Angular provides a mechanism to counter XSRF. When performing XHR requests, the
-     * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP
-     * header (`X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read the
-     * cookie, your server can be assured that the XHR came from JavaScript running on your domain.
-     * The header will not be set for cross-domain requests.
-     *
-     * To take advantage of this, your server needs to set a token in a JavaScript readable session
-     * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
-     * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
-     * that only JavaScript running on your domain could have sent the request. The token must be
-     * unique for each user and must be verifiable by the server (to prevent the JavaScript from
-     * making up its own tokens). We recommend that the token is a digest of your site's
-     * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography&#41;)
-     * for added security.
-     *
-     * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName
-     * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,
-     * or the per-request config object.
-     *
-     * In order to prevent collisions in environments where multiple Angular apps share the
-     * same domain or subdomain, we recommend that each application uses unique cookie name.
-     *
-     * @param {object} config Object describing the request to be made and how it should be
-     *    processed. The object has following properties:
-     *
-     *    - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
-     *    - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.
-     *    - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be serialized
-     *      with the `paramSerializer` and appended as GET parameters.
-     *    - **data** – `{string|Object}` – Data to be sent as the request message data.
-     *    - **headers** – `{Object}` – Map of strings or functions which return strings representing
-     *      HTTP headers to send to the server. If the return value of a function is null, the
-     *      header will not be sent. Functions accept a config object as an argument.
-     *    - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object.
-     *      To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`.
-     *      The handler will be called in the context of a `$apply` block.
-     *    - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload
-     *      object. To bind events to the XMLHttpRequest object, use `eventHandlers`.
-     *      The handler will be called in the context of a `$apply` block.
-     *    - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
-     *    - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
-     *    - **transformRequest** –
-     *      `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
-     *      transform function or an array of such functions. The transform function takes the http
-     *      request body and headers and returns its transformed (typically serialized) version.
-     *      See {@link ng.$http#overriding-the-default-transformations-per-request
-     *      Overriding the Default Transformations}
-     *    - **transformResponse** –
-     *      `{function(data, headersGetter, status)|Array.<function(data, headersGetter, status)>}` –
-     *      transform function or an array of such functions. The transform function takes the http
-     *      response body, headers and status and returns its transformed (typically deserialized) version.
-     *      See {@link ng.$http#overriding-the-default-transformations-per-request
-     *      Overriding the Default Transformations}
-     *    - **paramSerializer** - `{string|function(Object<string,string>):string}` - A function used to
-     *      prepare the string representation of request parameters (specified as an object).
-     *      If specified as string, it is interpreted as function registered with the
-     *      {@link $injector $injector}, which means you can create your own serializer
-     *      by registering it as a {@link auto.$provide#service service}.
-     *      The default serializer is the {@link $httpParamSerializer $httpParamSerializer};
-     *      alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike}
-     *    - **cache** – `{boolean|Object}` – A boolean value or object created with
-     *      {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response.
-     *      See {@link $http#caching $http Caching} for more information.
-     *    - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
-     *      that should abort the request when resolved.
-     *    - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the
-     *      XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
-     *      for more information.
-     *    - **responseType** - `{string}` - see
-     *      [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype).
-     *
-     * @returns {HttpPromise} Returns a {@link ng.$q `Promise}` that will be resolved to a response object
-     *                        when the request succeeds or fails.
-     *
-     *
-     * @property {Array.<Object>} pendingRequests Array of config objects for currently pending
-     *   requests. This is primarily meant to be used for debugging purposes.

-     *
-     * @description
-     *
-     * Compiles a string with markup into an interpolation function. This service is used by the
-     * HTML {@link ng.$compile $compile} service for data binding. See
-     * {@link ng.$interpolateProvider $interpolateProvider} for configuring the
-     * interpolation markup.
-     *
-     *
-     * ```js
-     *   var $interpolate = ...; // injected
-     *   var exp = $interpolate('Hello {{name | uppercase}}!');
-     *   expect(exp({name:'Angular'})).toEqual('Hello ANGULAR!');
-     * ```
-     *
-     * `$interpolate` takes an optional fourth argument, `allOrNothing`. If `allOrNothing` is
-     * `true`, the interpolation function will return `undefined` unless all embedded expressions
-     * evaluate to a value other than `undefined`.
-     *
-     * ```js
-     *   var $interpolate = ...; // injected
-     *   var context = {greeting: 'Hello', name: undefined };
-     *
-     *   // default "forgiving" mode
-     *   var exp = $interpolate('{{greeting}} {{name}}!');
-     *   expect(exp(context)).toEqual('Hello !');
-     *
-     *   // "allOrNothing" mode
-     *   exp = $interpolate('{{greeting}} {{name}}!', false, null, true);
-     *   expect(exp(context)).toBeUndefined();
-     *   context.name = 'Angular';
-     *   expect(exp(context)).toEqual('Hello Angular!');
-     * ```
-     *
-     * `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior.
-     *
-     * #### Escaped Interpolation
-     * $interpolate provides a mechanism for escaping interpolation markers. Start and end markers
-     * can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).
-     * It will be rendered as a regular start/end marker, and will not be interpreted as an expression
-     * or binding.
-     *
-     * This enables web-servers to prevent script injection attacks and defacing attacks, to some
-     * degree, while also enabling code examples to work without relying on the
-     * {@link ng.directive:ngNonBindable ngNonBindable} directive.
-     *
-     * **For security purposes, it is strongly encouraged that web servers escape user-supplied data,
-     * replacing angle brackets (&lt;, &gt;) with &amp;lt; and &amp;gt; respectively, and replacing all
-     * interpolation start/end markers with their escaped counterparts.**
-     *
-     * Escaped interpolation markers are only replaced with the actual interpolation markers in rendered
-     * output when the $interpolate service processes the text. So, for HTML elements interpolated
-     * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter
-     * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,
-     * this is typically useful only when user-data is used in rendering a template from the server, or
-     * when otherwise untrusted data is used by a directive.
-     *
-     * <example>
-     *  <file name="index.html">
-     *    <div ng-init="username='A user'">
-     *      <p ng-init="apptitle='Escaping demo'">{{apptitle}}: \{\{ username = "defaced value"; \}\}
-     *        </p>
-     *      <p><strong>{{username}}</strong> attempts to inject code which will deface the
-     *        application, but fails to accomplish their task, because the server has correctly
-     *        escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash)
-     *        characters.</p>
-     *      <p>Instead, the result of the attempted script injection is visible, and can be removed
-     *        from the database by an administrator.</p>

-     * @knownIssue
-     * It is currently not possible for an interpolated expression to contain the interpolation end
-     * symbol. For example, `{{ '}}' }}` will be incorrectly interpreted as `{{ ' }}` + `' }}`, i.e.
-     * an interpolated expression consisting of a single-quote (`'`) and the `' }}` string.
-     *
-     * @knownIssue
-     * All directives and components must use the standard `{{` `}}` interpolation symbols
-     * in their templates. If you change the application interpolation symbols the {@link $compile}
-     * service will attempt to denormalize the standard symbols to the custom symbols.
-     * The denormalization process is not clever enough to know not to replace instances of the standard
-     * symbols where they would not normally be treated as interpolation symbols. For example in the following
-     * code snippet the closing braces of the literal object will get incorrectly denormalized:
-     *
-     * ```
-     * <div data-context='{"context":{"id":3,"type":"page"}}">
-     * ```
-     *
-     * The workaround is to ensure that such instances are separated by whitespace:
-     * ```
-     * <div data-context='{"context":{"id":3,"type":"page"} }">
-     * ```

-      * You should take this into consideration and make sure to always cancel the interval at the

-// obtaining a reference to native JS functions such as the Function constructor.
+// AngularJS expressions are no longer sandboxed. So it is now even easier to access arbitrary JS code by

 //
 //   {}.toString.constructor('alert("evil JS code")')
 //
-// This sandboxing technique is not perfect and doesn't aim to be. The goal is to prevent exploits
-// against the expression language, but not to prevent exploits that were enabled by exposing
-// sensitive JavaScript or browser APIs on Scope. Exposing such objects on a Scope is never a good
-// practice and therefore we are not even trying to protect against interaction with an object
-// explicitly exposed in this way.
-//
-// In general, it is not possible to access a Window object from an angular expression unless a
-// window or some DOM object that has a reference to window is published onto a Scope.
-// Similarly we prevent invocations of function known to be dangerous, as well as assignments to
-// native objects.

+// content then it is possible that your application contains a security vulnerability to an XSS style attack.

+       * This can be used to optimize your application when you know that running those watchers
+       * is redundant.

+       * ample tests to ensure that bindings get updated as you expect.
+       *
+       * Some of the things to consider are:
+       *
+       * * Any external event on a directive/component will not trigger a digest while the hosting
+       *   scope is suspended - even if the event handler calls `$apply()` or `$rootScope.$digest()`.
+       * * Transcluded content exists on a scope that inherits from outside a directive but exists
+       *   as a child of the directive's containing scope. If the containing scope is suspended the

  *
  * ```
  *  angular.module('myApp', []).config(function($sceDelegateProvider) {
- *    $sceDelegateProvider.resourceUrlWhitelist([
+ *    $sceDelegateProvider.trustedResourceUrlList([
  *      // Allow same origin resource loads.
  *      'self',
  *      // Allow loading from our assets domain.  Notice the difference between * and **.
  *      'http://srv*.assets.example.com/**'
  *    ]);
  *
- *    // The blacklist overrides the whitelist so the open redirect here is blocked.
- *    $sceDelegateProvider.resourceUrlBlacklist([
+ *    // The banned resource URL list overrides the trusted resource URL list so the open redirect
+ *    // here is blocked.
+ *    $sceDelegateProvider.bannedResourceUrlList([
  *      'http://myapp.example.com/clickThru**'
  *    ]);
  *  });
  * ```
+ * Note that an empty trusted resource URL list will block every resource URL from being loaded, and will require
+ * you to manually mark each one as trusted with `$sce.trustAsResourceUrl`. However, templates
+ * requested by {@link ng.$templateRequest $templateRequest} that are present in
+ * {@link ng.$templateCache $templateCache} will not go through this check. If you have a mechanism
+ * to populate your templates in that cache at config time, then it is a good idea to remove 'self'
+ * from the trusted resource URL lsit. This helps to mitigate the security impact of certain types
+ * of issues, like for instance attacker-controlled `ng-includes`.

+ * ## Strict Contextual Escaping
+ *
+ * Strict Contextual Escaping (SCE) is a mode in which AngularJS constrains bindings to only render
+ * trusted values. Its goal is to assist in writing code in a way that (a) is secure by default, and
+ * (b) makes auditing for security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
+ *
+ * ### Overview
  *
- * Strict Contextual Escaping (SCE) is a mode in which AngularJS requires bindings in certain
- * contexts to result in a value that is marked as safe to use for that context.  One example of
- * such a context is binding arbitrary html controlled by the user via `ng-bind-html`.  We refer
- * to these contexts as privileged or SCE contexts.
+ * To systematically block XSS security bugs, AngularJS treats all values as untrusted by default in
+ * HTML or sensitive URL bindings. When binding untrusted values, AngularJS will automatically
+ * run security checks on them (sanitizations, trusted URL resource, depending on context), or throw
+ * when it cannot guarantee the security of the result. That behavior depends strongly on contexts:
+ * HTML can be sanitized, but template URLs cannot, for instance.
  *
- * As of version 1.2, Angular ships with SCE enabled by default.
+ * To illustrate this, consider the `ng-bind-html` directive. It renders its value directly as HTML:
+ * we call that the *context*. When given an untrusted input, AngularJS will attempt to sanitize it
+ * before rendering if a sanitizer is available, and throw otherwise. To bypass sanitization and
+ * render the input as-is, you will need to mark it as trusted for that context before attempting
+ * to bind it.
  *
- * Note:  When enabled (the default), IE<11 in quirks mode is not supported.  In this mode, IE<11 allow
- * one to execute arbitrary javascript by the use of the expression() syntax.  Refer
- * <http://blogs.msdn.com/b/ie/archive/2008/10/16/ending-expressions.aspx> to learn more about them.
- * You can ensure your document is in standards mode and not quirks mode by adding `<!doctype html>`
- * to the top of your HTML document.
+ * As of version 1.2, AngularJS ships with SCE enabled by default.
  *
- * SCE assists in writing code in a way that (a) is secure by default and (b) makes auditing for
- * security vulnerabilities such as XSS, clickjacking, etc. a lot easier.

  *
  * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
- * $sce.getTrusted(context, value)} rather than to the value directly.  Directives use {@link

+   * @ngdoc input
+   * @name input[range]
+   *
+   * @description
+   * Native range input with validation and transformation.
+   *
+   * The model for the range input must always be a `Number`.
+   *
+   * IE9 and other browsers that do not support the `range` type fall back
+   * to a text input without any default values for `min`, `max` and `step`. Model binding,
+   * validation and number parsing are nevertheless supported.
+   *
+   * Browsers that support range (latest Chrome, Safari, Firefox, Edge) treat `input[range]`
+   * in a way that never allows the input to hold an invalid value. That means:
+   * - any non-numerical value is set to `(max + min) / 2`.
+   * - any numerical value that is less than the current min val, or greater than the current max val
+   * is set to the min / max val respectively.
+   * - additionally, the current `step` is respected, so the nearest value that satisfies a step
+   * is used.
+   *
+   * See the [HTML Spec on input[type=range]](https://www.w3.org/TR/html5/forms.html#range-state-(type=range))
+   * for more info.
+   *
+   * This has the following consequences for AngularJS:
+   *
+   * Since the element value should always reflect the current model value, a range input
+   * will set the bound ngModel expression to the value that the browser has set for the
+   * input element. For example, in the following input `<input type="range" ng-model="model.value">`,
+   * if the application sets `model.value = null`, the browser will set the input to `'50'`.
+   * AngularJS will then set the model to `50`, to prevent input and model value being out of sync.
+   *
+   * That means the model for range will immediately be set to `50` after `ngModel` has been
+   * initialized. It also means a range input can never have the required error.
+   *
+   * This does not only affect changes to the model value, but also to the values of the `min`,
+   * `max`, and `step` attributes. When these change in a way that will cause the browser to modify
+   * the input value, AngularJS will also update the model value.
+   *
+   * Automatic value adjustment also means that a range input element can never have the `required`,
+   * `min`, or `max` errors.
+   *
+   * However, `step` is currently only fully implemented by Firefox. Other browsers have problems
+   * when the step value changes dynamically - they do not adjust the element value correctly, but
+   * instead may set the `stepMismatch` error. If that's the case, the AngularJS will set the `step`
+   * error on the input, and set the model to `undefined`.
+   *
+   * Note that `input[range]` is not compatible with`ngMax`, `ngMin`, and `ngStep`, because they do
+   * not set the `min` and `max` attributes, which means that the browser won't automatically adjust
+   * the input value based on their values, and will always assume min = 0, max = 100, and step = 1.

+   * @param {string=} max Sets the `max` validation to ensure that the value entered is less than `max`.

- * @description
- * The `ngBind` attribute tells Angular to replace the text content of the specified HTML element
- * with the value of a given expression, and to update the text content when the value of that
- * expression changes.
- *
- * Typically, you don't use `ngBind` directly, but instead you use the double curly markup like
- * `{{ expression }}` which is similar but less verbose.
- *
- * It is preferable to use `ngBind` instead of `{{ expression }}` if a template is momentarily
- * displayed by the browser in its raw state before Angular compiles it. Since `ngBind` is an
- * element attribute, it makes the bindings invisible to the user while the page is loading.

- * @ngdoc directive
- * @name ngClass
- * @restrict AC
- *
- * @description
- * The `ngClass` directive allows you to dynamically set CSS classes on an HTML element by databinding
- * an expression that represents all classes to be added.
- *
- * The directive operates in three different ways, depending on which of three types the expression
- * evaluates to:
- *
- * 1. If the expression evaluates to a string, the string should be one or more space-delimited class
- * names.
- *
- * 2. If the expression evaluates to an object, then for each key-value pair of the
- * object with a truthy value the corresponding key is used as a class name.
- *
- * 3. If the expression evaluates to an array, each element of the array should either be a string as in
- * type 1 or an object as in type 2. This means that you can mix strings and objects together in an array
- * to give you more control over what CSS classes appear. See the code below for an example of this.
- *
- *
- * The directive won't add duplicate classes if a particular class was already set.
- *
- * When the expression changes, the previously added classes are removed and only then are the
- * new classes added.
- *
- * @knownIssue
- * You should not use {@link guide/interpolation interpolation} in the value of the `class`
- * attribute, when using the `ngClass` directive on the same element.
- * See {@link guide/interpolation#known-issues here} for more info.
- *
- * @animations
- * | Animation                        | Occurs                              |
- * |----------------------------------|-------------------------------------|
- * | {@link ng.$animate#addClass addClass}       | just before the class is applied to the element   |
- * | {@link ng.$animate#removeClass removeClass} | just before the class is removed from the element |
- *
- * @element ANY
- * @param {expression} ngClass {@link guide/expression Expression} to eval. The result
- *   of the evaluation can be a string representing space delimited class
- *   names, an array, or a map of class names to boolean values. In the case of a map, the
- *   names of the properties whose values are truthy will be added as css classes to the
- *   element.
- *
- * @example Example that demonstrates basic bindings via ngClass directive.

-   ## Animations
-
-   The example below demonstrates how to perform animations using ngClass.
-
-   <example module="ngAnimate" deps="angular-animate.js" animations="true">
-     <file name="index.html">
-      <input id="setbtn" type="button" value="set" ng-click="myVar='my-class'">
-      <input id="clearbtn" type="button" value="clear" ng-click="myVar=''">
-      <br>
-      <span class="base-class" ng-class="myVar">Sample Text</span>
-     </file>
-     <file name="style.css">
-       .base-class {
-         transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;
-       }
-
-       .base-class.my-class {
-         color: red;
-         font-size:3em;
-       }
-     </file>
-     <file name="protractor.js" type="protractor">
-       it('should check ng-class', function() {
-         expect(element(by.css('.base-class')).getAttribute('class')).not.
-           toMatch(/my-class/);
-
-         element(by.id('setbtn')).click();
-
-         expect(element(by.css('.base-class')).getAttribute('class')).
-           toMatch(/my-class/);
-
-         element(by.id('clearbtn')).click();
-
-         expect(element(by.css('.base-class')).getAttribute('class')).not.
-           toMatch(/my-class/);
-       });
-     </file>
-   </example>
-
-
-   ## ngClass and pre-existing CSS3 Transitions/Animations
-   The ngClass directive still supports CSS3 Transitions/Animations even if they do not follow the ngAnimate CSS naming structure.
-   Upon animation ngAnimate will apply supplementary CSS classes to track the start and end of an animation, but this will not hinder
-   any pre-existing CSS transitions already on the element. To get an idea of what happens during a class-based animation, be sure
-   to view the step by step details of {@link $animate#addClass $animate.addClass} and
-   {@link $animate#removeClass $animate.removeClass}.

- * @restrict AC
- *
- * @description
- * The `ngCloak` directive is used to prevent the Angular html template from being briefly
- * displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
- * directive to avoid the undesirable flicker effect caused by the html template display.
- *
- * The directive can be applied to the `<body>` element, but the preferred usage is to apply
- * multiple `ngCloak` directives to small portions of the page to permit progressive rendering
- * of the browser view.
- *
- * `ngCloak` works in cooperation with the following css rule embedded within `angular.js` and
- * `angular.min.js`.
- * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
- *
- * ```css
- * [ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
- *   display: none !important;
- * }
- * ```
- *
- * When this css rule is loaded by the browser, all html elements (including their children) that
- * are tagged with the `ngCloak` directive are hidden. When Angular encounters this directive
- * during the compilation of the template it deletes the `ngCloak` element attribute, making
- * the compiled element visible.
- *
- * For the best result, the `angular.js` script must be loaded in the head section of the html
- * document; alternatively, the css rule above must be included in the external stylesheet of the
- * application.

-/**
- * @ngdoc directive
- * @name ngController
- *
- * @description
- * The `ngController` directive attaches a controller class to the view. This is a key aspect of how angular
- * supports the principles behind the Model-View-Controller design pattern.
- *
- * MVC components in angular:
- *
- * * Model — Models are the properties of a scope; scopes are attached to the DOM where scope properties
- *   are accessed through bindings.
- * * View — The template (HTML with data bindings) that is rendered into the View.
- * * Controller — The `ngController` directive specifies a Controller class; the class contains business
- *   logic behind the application to decorate the scope with functions and values
- *
- * Note that you can also attach controllers to the DOM by declaring it in a route definition
- * via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller
- * again using `ng-controller` in the template itself.  This will cause the controller to be attached
- * and executed twice.
- *
- * @element ANY
- * @scope
- * @priority 500
- * @param {expression} ngController Name of a constructor function registered with the current
- * {@link ng.$controllerProvider $controllerProvider} or an {@link guide/expression expression}
- * that on the current scope evaluates to a constructor function.
- *
- * The controller instance can be published into a scope property by specifying
- * `ng-controller="as propertyName"`.
- *
- * If the current `$controllerProvider` is configured to use globals (via
- * {@link ng.$controllerProvider#allowGlobals `$controllerProvider.allowGlobals()` }), this may
- * also be the name of a globally accessible constructor function (not recommended).
- *
- * @example
- * Here is a simple form for editing user contact information. Adding, removing, clearing, and
- * greeting are methods declared on the controller (see source tab). These methods can
- * easily be called from the angular markup. Any changes to the data are automatically reflected
- * in the View without the need for a manual update.
- *
- * Two different declaration styles are included below:
- *
- * * one binds methods and properties directly onto the controller using `this`:
- * `ng-controller="SettingsController1 as settings"`
- * * one injects `$scope` into the controller:
- * `ng-controller="SettingsController2"`
- *
- * The second option is more common in the Angular community, and is generally used in boilerplates
- * and in this guide. However, there are advantages to binding properties directly to the controller
- * and avoiding scope.
- *
- * * Using `controller as` makes it obvious which controller you are accessing in the template when
- * multiple controllers apply to an element.
- * * If you are writing your controllers as classes you have easier access to the properties and
- * methods, which will appear on the scope, from inside the controller code.
- * * Since there is always a `.` in the bindings, you don't have to worry about prototypal
- * inheritance masking primitives.
- *
- * This example demonstrates the `controller as` syntax.

-/**
- * @ngdoc directive
- * @name ngCsp
- *
- * @element html
- * @description
- *
- * Angular has some features that can break certain
- * [CSP (Content Security Policy)](https://developer.mozilla.org/en/Security/CSP) rules.
- *
- * If you intend to implement these rules then you must tell Angular not to use these features.
- *
- * This is necessary when developing things like Google Chrome Extensions or Universal Windows Apps.
- *
- *
- * The following rules affect Angular:
- *
- * * `unsafe-eval`: this rule forbids apps to use `eval` or `Function(string)` generated functions
- * (among other things). Angular makes use of this in the {@link $parse} service to provide a 30%
- * increase in the speed of evaluating Angular expressions.
- *
- * * `unsafe-inline`: this rule forbids apps from inject custom styles into the document. Angular
- * makes use of this to include some CSS rules (e.g. {@link ngCloak} and {@link ngHide}).
- * To make these directives work when a CSP rule is blocking inline styles, you must link to the
- * `angular-csp.css` in your HTML manually.
- *
- * If you do not provide `ngCsp` then Angular tries to autodetect if CSP is blocking unsafe-eval
- * and automatically deactivates this feature in the {@link $parse} service. This autodetection,
- * however, triggers a CSP error to be logged in the console:
- *
- * ```
- * Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of
- * script in the following Content Security Policy directive: "default-src 'self'". Note that
- * 'script-src' was not explicitly set, so 'default-src' is used as a fallback.
- * ```
- *
- * This error is harmless but annoying. To prevent the error from showing up, put the `ngCsp`
- * directive on an element of the HTML document that appears before the `<script>` tag that loads
- * the `angular.js` file.
- *
- * *Note: This directive is only available in the `ng-csp` and `data-ng-csp` attribute form.*
- *
- * You can specify which of the CSP related Angular features should be deactivated by providing
- * a value for the `ng-csp` attribute. The options are as follows:
- *
- * * no-inline-style: this stops Angular from injecting CSS styles into the DOM
- *
- * * no-unsafe-eval: this stops Angular from optimizing $parse with unsafe eval of strings
- *
- * You can use these values in the following combinations:
- *
- *
- * * No declaration means that Angular will assume that you can do inline styles, but it will do
- * a runtime check for unsafe-eval. E.g. `<body>`. This is backwardly compatible with previous versions
- * of Angular.
- *
- * * A simple `ng-csp` (or `data-ng-csp`) attribute will tell Angular to deactivate both inline
- * styles and unsafe eval. E.g. `<body ng-csp>`. This is backwardly compatible with previous versions
- * of Angular.
- *
- * * Specifying only `no-unsafe-eval` tells Angular that we must not use eval, but that we can inject
- * inline styles. E.g. `<body ng-csp="no-unsafe-eval">`.
- *
- * * Specifying only `no-inline-style` tells Angular that we must not inject styles, but that we can
- * run eval - no automatic check for unsafe eval will occur. E.g. `<body ng-csp="no-inline-style">`
- *
- * * Specifying both `no-unsafe-eval` and `no-inline-style` tells Angular that we must not inject
- * styles nor use eval, which is the same as an empty: ng-csp.
- * E.g.`<body ng-csp="no-inline-style;no-unsafe-eval">`
- *
- * @example
- * This example shows how to apply the `ngCsp` directive to the `html` tag.
-   ```html
-     <!doctype html>
-     <html ng-app ng-csp>
-     ...
-     ...
-     </html>
-   ```
-  * @example
-      // Note: the suffix `.csp` in the example name triggers
-      // csp mode in our http server!

-/**
- * @ngdoc directive
- * @name ngIf
- * @restrict A
- * @multiElement
- *
- * @description
- * The `ngIf` directive removes or recreates a portion of the DOM tree based on an
- * {expression}. If the expression assigned to `ngIf` evaluates to a false
- * value then the element is removed from the DOM, otherwise a clone of the
- * element is reinserted into the DOM.
- *
- * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the
- * element in the DOM rather than changing its visibility via the `display` css property.  A common
- * case when this difference is significant is when using css selectors that rely on an element's
- * position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes.
- *
- * Note that when an element is removed using `ngIf` its scope is destroyed and a new scope
- * is created when the element is restored.  The scope created within `ngIf` inherits from
- * its parent scope using
- * [prototypal inheritance](https://github.com/angular/angular.js/wiki/Understanding-Scopes#javascript-prototypal-inheritance).
- * An important implication of this is if `ngModel` is used within `ngIf` to bind to
- * a javascript primitive defined in the parent scope. In this case any modifications made to the
- * variable within the child scope will override (hide) the value in the parent scope.
- *
- * Also, `ngIf` recreates elements using their compiled state. An example of this behavior
- * is if an element's class attribute is directly modified after it's compiled, using something like
- * jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element
- * the added class will be lost because the original compiled state is used to regenerate the element.
- *
- * Additionally, you can provide animations via the `ngAnimate` module to animate the `enter`
- * and `leave` effects.
- *
- * @animations
- * | Animation                        | Occurs                               |
- * |----------------------------------|-------------------------------------|
- * | {@link ng.$animate#enter enter}  | just after the `ngIf` contents change and a new DOM element is created and injected into the `ngIf` container |
- * | {@link ng.$animate#leave leave}  | just before the `ngIf` contents are removed from the DOM |
- *
- * @element ANY
- * @scope
- * @priority 600
- * @param {expression} ngIf If the {@link guide/expression expression} is falsy then
- *     the element is removed from the DOM tree. If it is truthy a copy of the compiled
- *     element is added to the DOM tree.
- *
- * @example
-  <example module="ngAnimate" deps="angular-animate.js" animations="true">

- * The `ngInit` directive allows you to evaluate an expression in the
- * current scope.
- *
- * <div class="alert alert-danger">
- * This directive can be abused to add unnecessary amounts of logic into your templates.
- * There are only a few appropriate uses of `ngInit`, such as for aliasing special properties of
- * {@link ng.directive:ngRepeat `ngRepeat`}, as seen in the demo below; and for injecting data via
- * server side scripting. Besides these few cases, you should use {@link guide/controller controllers}
- * rather than `ngInit` to initialize values on a scope.
- * </div>
- *
- * <div class="alert alert-warning">
- * **Note**: If you have assignment in `ngInit` along with a {@link ng.$filter `filter`}, make
- * sure you have parentheses to ensure correct operator precedence:
- * <pre class="prettyprint">
- * `<div ng-init="test1 = ($index | toString)"></div>`
- * </pre>
- * </div>
- *
- * @priority 450
- *
- * @element ANY

-/**
- * @ngdoc directive
- * @name ngList
- *
- * @description
- * Text input that converts between a delimited string and an array of strings. The default
- * delimiter is a comma followed by a space - equivalent to `ng-list=", "`. You can specify a custom
- * delimiter as the value of the `ngList` attribute - for example, `ng-list=" | "`.
- *
- * The behaviour of the directive is affected by the use of the `ngTrim` attribute.
- * * If `ngTrim` is set to `"false"` then whitespace around both the separator and each
- *   list item is respected. This implies that the user of the directive is responsible for
- *   dealing with whitespace but also allows you to use whitespace as a delimiter, such as a
- *   tab or newline character.
- * * Otherwise whitespace around the delimiter is ignored when splitting (although it is respected
- *   when joining the list items back together) and whitespace around each list item is stripped
- *   before it is added to the model.

- *
- * `NgModelController` provides API for the {@link ngModel `ngModel`} directive.
- * The controller contains services for data-binding, validation, CSS updates, and value formatting
- * and parsing. It purposefully does not contain any logic which deals with DOM rendering or
- * listening to DOM events.
- * Such DOM related logic should be provided by other directives which make use of
- * `NgModelController` for data-binding to control elements.
- * Angular provides this DOM logic for most {@link input `input`} elements.
- * At the end of this page you can find a {@link ngModel.NgModelController#custom-control-example
- * custom control example} that uses `ngModelController` to bind to `contenteditable` elements.
- *
- * @example
- * ### Custom Control Example
- * This example shows how to use `NgModelController` with a custom control to achieve
- * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
- * collaborate together to achieve the desired result.
- *
- * `contenteditable` is an HTML5 attribute, which tells the browser to let the element
- * contents be edited in place by the user.
- *
- * We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize}
- * module to automatically remove "bad" content like inline event listener (e.g. `<span onclick="...">`).
- * However, as we are using `$sce` the model can still decide to provide unsafe content if it marks
- * that content using the `$sce` service.
- *
- * <example name="NgModelController" module="customControl" deps="angular-sanitize.js">
-    <file name="style.css">
-      [contenteditable] {
-        border: 1px solid black;
-        background-color: white;
-        min-height: 20px;
-      }
-
-      .ng-invalid {
-        border: 1px solid red;
-      }
-
-    </file>
-    <file name="script.js">
-      angular.module('customControl', ['ngSanitize']).
-        directive('contenteditable', ['$sce', function($sce) {
-          return {
-            restrict: 'A', // only activate on element attribute

-   * Cancel an update and reset the input element's value to prevent an update to the `$modelValue`,
-   * which may be caused by a pending debounced event or because the input is waiting for a some
-   * future event.
-   *
-   * If you have an input that uses `ng-model-options` to set up debounced updates or updates that
-   * depend on special events such as blur, you can have a situation where there is a period when
-   * the `$viewValue` is out of sync with the ngModel's `$modelValue`.
-   *
-   * In this case, you can use `$rollbackViewValue()` to manually cancel the debounced / future update
-   * and reset the input to the last committed view value.
-   *
-   * It is also possible that you run into difficulties if you try to update the ngModel's `$modelValue`
-   * programmatically before these debounced/future events have resolved/occurred, because Angular's
-   * dirty checking mechanism is not able to tell whether the model has actually changed or not.
-   *
-   * The `$rollbackViewValue()` method should be called before programmatically changing the model of an
-   * input which may have such events pending. This is important in order to make sure that the
-   * input field will be updated with the new model value and any pending operations are cancelled.

-   * @ngdoc method
-   * @name ngModel.NgModelController#$setViewValue
-   *
-   * @description
-   * Update the view value.
-   *
-   * This method should be called when a control wants to change the view value; typically,
-   * this is done from within a DOM event handler. For example, the {@link ng.directive:input input}
-   * directive calls it when the value of the input changes and {@link ng.directive:select select}
-   * calls it when an option is selected.
-   *
-   * When `$setViewValue` is called, the new `value` will be staged for committing through the `$parsers`
-   * and `$validators` pipelines. If there are no special {@link ngModelOptions} specified then the staged
-   * value sent directly for processing, finally to be applied to `$modelValue` and then the
-   * **expression** specified in the `ng-model` attribute. Lastly, all the registered change listeners,
-   * in the `$viewChangeListeners` list, are called.
-   *
-   * In case the {@link ng.directive:ngModelOptions ngModelOptions} directive is used with `updateOn`
-   * and the `default` trigger is not listed, all those actions will remain pending until one of the
-   * `updateOn` events is triggered on the DOM element.
-   * All these actions will be debounced if the {@link ng.directive:ngModelOptions ngModelOptions}
-   * directive is used with a custom debounce for this particular event.
-   * Note that a `$digest` is only triggered once the `updateOn` events are fired, or if `debounce`
-   * is specified, once the timer runs out.
-   *
-   * When used with standard inputs, the view value will always be a string (which is in some cases
-   * parsed into another type, such as a `Date` object for `input[date]`.)
-   * However, custom controls might also pass objects to this method. In this case, we should make
-   * a copy of the object before passing it to `$setViewValue`. This is because `ngModel` does not
-   * perform a deep watch of objects, it only looks for a change of identity. If you only change
-   * the property of the object then ngModel will not realize that the object has changed and
-   * will not invoke the `$parsers` and `$validators` pipelines. For this reason, you should
-   * not change properties of the copy once it has been passed to `$setViewValue`.
-   * Otherwise you may cause the model value on the scope to change incorrectly.
-   *
-   * <div class="alert alert-info">
-   * In any case, the value passed to the method should always reflect the current value
-   * of the control. For example, if you are calling `$setViewValue` for an input element,
-   * you should pass the input DOM value. Otherwise, the control and the scope model become
-   * out of sync. It's also important to note that `$setViewValue` does not call `$render` or change
-   * the control's DOM value in any way. If we want to change the control's DOM value
-   * programmatically, we should update the `ngModel` scope expression. Its new value will be
-   * picked up by the model controller, which will run it through the `$formatters`, `$render` it
-   * to update the DOM, and finally call `$validate` on it.
-   * </div>

-/**
- * @ngdoc directive
- * @name ngModel
- *
- * @element input
- * @priority 1
- *
- * @description
- * The `ngModel` directive binds an `input`,`select`, `textarea` (or custom form control) to a
- * property on the scope using {@link ngModel.NgModelController NgModelController},
- * which is created and exposed by this directive.
- *
- * `ngModel` is responsible for:
- *
- * - Binding the view into the model, which other directives such as `input`, `textarea` or `select`
- *   require.
- * - Providing validation behavior (i.e. required, number, email, url).
- * - Keeping the state of the control (valid/invalid, dirty/pristine, touched/untouched, validation errors).
- * - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`, `ng-touched`,
- *   `ng-untouched`, `ng-empty`, `ng-not-empty`) including animations.
- * - Registering the control with its parent {@link ng.directive:form form}.
- *
- * Note: `ngModel` will try to bind to the property given by evaluating the expression on the
- * current scope. If the property doesn't already exist on this scope, it will be created
- * implicitly and added to the scope.
- *
- * For best practices on using `ngModel`, see:
- *
- *  - [Understanding Scopes](https://github.com/angular/angular.js/wiki/Understanding-Scopes)
- *
- * For basic examples, how to use `ngModel`, see:
- *
- *  - {@link ng.directive:input input}
- *    - {@link input[text] text}
- *    - {@link input[checkbox] checkbox}
- *    - {@link input[radio] radio}
- *    - {@link input[number] number}
- *    - {@link input[email] email}
- *    - {@link input[url] url}
- *    - {@link input[date] date}
- *    - {@link input[datetime-local] datetime-local}
- *    - {@link input[time] time}
- *    - {@link input[month] month}
- *    - {@link input[week] week}
- *  - {@link ng.directive:select select}
- *  - {@link ng.directive:textarea textarea}
- *
- * # Complex Models (objects or collections)
- *
- * By default, `ngModel` watches the model by reference, not value. This is important to know when
- * binding inputs to models that are objects (e.g. `Date`) or collections (e.g. arrays). If only properties of the
- * object or collection change, `ngModel` will not be notified and so the input will not be  re-rendered.
- *
- * The model must be assigned an entirely new object or collection before a re-rendering will occur.
- *
- * Some directives have options that will cause them to use a custom `$watchCollection` on the model expression
- * - for example, `ngOptions` will do so when a `track by` clause is included in the comprehension expression or
- * if the select is given the `multiple` attribute.
- *
- * The `$watchCollection()` method only does a shallow comparison, meaning that changing properties deeper than the
- * first level of the object (or only changing the properties of an item in the collection if it's an array) will still
- * not trigger a re-rendering of the model.
- *
- * # CSS classes
- * The following CSS classes are added and removed on the associated input/select/textarea element
- * depending on the validity of the model.
- *
- *  - `ng-valid`: the model is valid
- *  - `ng-invalid`: the model is invalid
- *  - `ng-valid-[key]`: for each valid key added by `$setValidity`
- *  - `ng-invalid-[key]`: for each invalid key added by `$setValidity`
- *  - `ng-pristine`: the control hasn't been interacted with yet
- *  - `ng-dirty`: the control has been interacted with
- *  - `ng-touched`: the control has been blurred
- *  - `ng-untouched`: the control hasn't been blurred
- *  - `ng-pending`: any `$asyncValidators` are unfulfilled
- *  - `ng-empty`: the view does not contain a value or the value is deemed "empty", as defined
- *     by the {@link ngModel.NgModelController#$isEmpty} method
- *  - `ng-not-empty`: the view contains a non-empty value
- *
- * Keep in mind that ngAnimate can detect each of these classes when added and removed.
- *
- * ## Animation Hooks
- *
- * Animations within models are triggered when any of the associated CSS classes are added and removed
- * on the input element which is attached to the model. These classes include: `.ng-pristine`, `.ng-dirty`,
- * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.
- * The animations that are triggered within ngModel are similar to how they work in ngClass and
- * animations can be hooked into using CSS transitions, keyframes as well as JS animations.
- *
- * The following example shows a simple way to utilize CSS transitions to style an input element
- * that has been rendered as invalid after it has been validated:
- *
- * <pre>
- * //be sure to include ngAnimate as a module to hook into more
- * //advanced animations
- * .my-input {
- *   transition:0.5s linear all;
- *   background: white;
- * }
- * .my-input.ng-invalid {
- *   background: red;
- *   color:white;
- * }
- * </pre>
- *
- * @example
- * <example deps="angular-animate.js" animations="true" fixBase="true" module="inputExample">
-     <file name="index.html">
-       <script>
-        angular.module('inputExample', [])
-          .controller('ExampleController', ['$scope', function($scope) {
-            $scope.val = '1';
-          }]);
-       </script>
-       <style>
-         .my-input {
-           transition:all linear 0.5s;
-           background: transparent;
-         }
-         .my-input.ng-invalid {
-           color:white;
-           background: red;
-         }
-       </style>
-       <p id="inputDescription">
-        Update input to see transitions when valid/invalid.
-        Integer is a valid value.
-       </p>
-       <form name="testForm" ng-controller="ExampleController">
-         <input ng-model="val" ng-pattern="/^\d+$/" name="anim" class="my-input"
-                aria-describedby="inputDescription" />
-       </form>
-     </file>
- * </example>
- *
- * ## Binding to a getter/setter
- *
- * Sometimes it's helpful to bind `ngModel` to a getter/setter function.  A getter/setter is a
- * function that returns a representation of the model when called with zero arguments, and sets
- * the internal state of a model when called with an argument. It's sometimes useful to use this
- * for models that have an internal representation that's different from what the model exposes
- * to the view.
- *
- * <div class="alert alert-success">
- * **Best Practice:** It's best to keep getters fast because Angular is likely to call them more
- * frequently than other parts of your code.
- * </div>
- *
- * You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that
- * has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to
- * a `<form>`, which will enable this behavior for all `<input>`s within it. See
- * {@link ng.directive:ngModelOptions `ngModelOptions`} for more.
- *
- * The following example shows how to use `ngModel` with a getter/setter:
- *
- * @example
- * <example name="ngModel-getter-setter" module="getterSetterExample">
-     <file name="index.html">
-       <div ng-controller="ExampleController">
-         <form name="userForm">
-           <label>Name:
-             <input type="text" name="userName"
-                    ng-model="user.name"
-                    ng-model-options="{ getterSetter: true }" />
-           </label>
-         </form>
-         <pre>user.name = <span ng-bind="user.name()"></span></pre>
-       </div>
-     </file>
-     <file name="app.js">
-       angular.module('getterSetterExample', [])
-         .controller('ExampleController', ['$scope', function($scope) {
-           var _name = 'Brian';
-           $scope.user = {
-             name: function(newName) {
-              // Note that newName can be undefined for two reasons:
-              // 1. Because it is called as a getter and thus called with no arguments
-              // 2. Because the property should actually be set to undefined. This happens e.g. if the
-              //    input is invalid
-              return arguments.length ? (_name = newName) : _name;
-             }
-           };
-         }]);

-/**
- * @ngdoc directive
- * @name ngModelOptions
- *
- * @description
- * Allows tuning how model updates are done. Using `ngModelOptions` you can specify a custom list of
- * events that will trigger a model update and/or a debouncing delay so that the actual update only
- * takes place when a timer expires; this timer will be reset after another change takes place.
- *
- * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might
- * be different from the value in the actual model. This means that if you update the model you
- * should also invoke {@link ngModel.NgModelController `$rollbackViewValue`} on the relevant input field in
- * order to make sure it is synchronized with the model and that any debounced action is canceled.
- *
- * The easiest way to reference the control's {@link ngModel.NgModelController `$rollbackViewValue`}
- * method is by making sure the input is placed inside a form that has a `name` attribute. This is
- * important because `form` controllers are published to the related scope under the name in their
- * `name` attribute.
- *
- * Any pending changes will take place immediately when an enclosing form is submitted via the
- * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
- * to have access to the updated model.
- *
- * `ngModelOptions` has an effect on the element it's declared on and its descendants.
- *
- * @param {Object} ngModelOptions options to apply to the current model. Valid keys are:
- *   - `updateOn`: string specifying which event should the input be bound to. You can set several
- *     events using an space delimited list. There is a special event called `default` that
- *     matches the default events belonging of the control.
- *   - `debounce`: integer value which contains the debounce model update value in milliseconds. A
- *     value of 0 triggers an immediate update. If an object is supplied instead, you can specify a
- *     custom value for each event. For example:
- *     `ng-model-options="{ updateOn: 'default blur', debounce: { 'default': 500, 'blur': 0 } }"`
- *   - `allowInvalid`: boolean value which indicates that the model can be set with values that did
- *     not validate correctly instead of the default behavior of setting the model to undefined.
- *   - `getterSetter`: boolean value which determines whether or not to treat functions bound to
-       `ngModel` as getters/setters.
- *   - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for
- *     `<input type="date">`, `<input type="time">`, ... . It understands UTC/GMT and the
- *     continental US time zone abbreviations, but for general use, use a time zone offset, for
- *     example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
- *     If not specified, the timezone of the browser will be used.
- *
- * @example
-
-  The following example shows how to override immediate updates. Changes on the inputs within the
-  form will update the model only when the control loses focus (blur event). If `escape` key is
-  pressed while the input field is focused, the value is reset to the value in the current model.

- * If you do need to repeat duplicate items, you can substitute the default tracking behavior
- * with your own using the `track by` expression.
+ * <div class="alert alert-success">
+ * **Best Practice:** If you are working with objects that have a unique identifier property, you
+ * should track by this identifier instead of the object instance,
+ * e.g. `item in items track by item.id`.
+ * Should you reload your data later, `ngRepeat` will not have to rebuild the DOM elements for items
+ * it has already rendered, even if the JavaScript objects in the collection have been substituted
+ * for new ones. For large collections, this significantly improves rendering performance.
+ * </div>
  *
- * For example, you may track items by the index of each item in the collection, using the
- * special scope property `$index`:
- * ```html
- *    <div ng-repeat="n in [42, 42, 43, 43] track by $index">
- *      {{n}}
- *    </div>
- * ```
+ * ### Effects of DOM Element re-use
  *
- * You may also use arbitrary expressions in `track by`, including references to custom functions
- * on the scope:
- * ```html
- *    <div ng-repeat="n in [42, 42, 43, 43] track by myTrackingFunction(n)">
- *      {{n}}
- *    </div>
- * ```
+ * When DOM elements are re-used, ngRepeat updates the scope for the element, which will
+ * automatically update any active bindings on the template. However, other
+ * functionality will not be updated, because the element is not re-created:
  *
- * <div class="alert alert-success">
- * If you are working with objects that have an identifier property, you should track
- * by the identifier instead of the whole object. Should you reload your data later, `ngRepeat`

- * JavaScript objects in the collection have been substituted for new ones. For large collections,
- * this significantly improves rendering performance. If you don't have a unique identifier,
- * `track by $index` can also provide a performance boost.
- * </div>
- * ```html
- *    <div ng-repeat="model in collection track by model.id">
- *      {{model.name}}
- *    </div>
- * ```
+ * - Directives are not re-compiled
+ * - {@link guide/expression#one-time-binding one-time expressions} on the repeated template are not
+ * updated if they have stabilized.
  *
- * When no `track by` expression is provided, it is equivalent to tracking by the built-in
- * `$id` function, which tracks items by their identity:
- * ```html
- *    <div ng-repeat="obj in collection track by $id(obj)">
- *      {{obj.prop}}
- *    </div>
- * ```
+ * The above affects all kinds of element re-use due to tracking, but may be especially visible
+ * when tracking by `$index` due to the way ngRepeat re-uses elements.
  *
- * <div class="alert alert-warning">

+ * ## Special repeat start and end points
  * To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending
  * the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively.
  * The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on)

+ * ### Flickering when using ngShow to toggle between elements
+ *
+ * When using {@link ngShow} and / or {@link ngHide} to toggle between elements, it can
+ * happen that both the element to show and the element to hide are visible for a very short time.
+ *
+ * This usually happens when the {@link ngAnimate ngAnimate module} is included, but no actual animations
+ * are defined for {@link ngShow} / {@link ngHide}. Internet Explorer is affected more often than
+ * other browsers.
+ *
+ * There are several way to mitigate this problem:
+ *
+ * - {@link guide/animations#how-to-selectively-enable-disable-and-skip-animations Disable animations on the affected elements}.
+ * - Use {@link ngIf} or {@link ngSwitch} instead of {@link ngShow} / {@link ngHide}.
+ * - Use the special CSS selector `ng-hide.ng-hide-animate` to set `{display: none}` or similar on the affected elements.
+ * - Use `ng-class="{'ng-hide': expression}` instead of instead of {@link ngShow} / {@link ngHide}.
+ * - Define an animation on the affected elements.

- * added `<option>` elements, perhaps by an `ngRepeat` directive.
+ * The controller for the {@link ng.select select} directive. The controller exposes
+ * a few utility methods that can be used to augment the behavior of a regular or an
+ * {@link ng.ngOptions ngOptions} select element.
+ *
+ * @example
+ * ### Set a custom error when the unknown option is selected
+ *
+ * This example sets a custom error "unknownValue" on the ngModelController

+ * that is not matched by any option.
