-// TaskList Behavior
-//
-/*= provides tasklist:enabled */
-/*= provides tasklist:disabled */
-/*= provides tasklist:change */
-/*= provides tasklist:changed */
-//
-//
-// Enables Task List update behavior.
-//
-// ### Example Markup
-//
-// <div class="js-task-list-container">
-// <ul class="task-list">
-// <li class="task-list-item">
-// <input type="checkbox" class="js-task-list-item-checkbox" disabled />
-// text
-// </li>
-// </ul>
-// <form>
-// <textarea class="js-task-list-field">- [ ] text</textarea>
-// </form>
-// </div>
-//
-// ### Specification
-//
-// TaskLists MUST be contained in a `(div).js-task-list-container`.
-//
-// TaskList Items SHOULD be an a list (`UL`/`OL`) element.
-//
-// Task list items MUST match `(input).task-list-item-checkbox` and MUST be
-// `disabled` by default.
-//
-// TaskLists MUST have a `(textarea).js-task-list-field` form element whose
-// `value` attribute is the source (Markdown) to be udpated. The source MUST
-// follow the syntax guidelines.
-//
-// TaskList updates trigger `tasklist:change` events. If the change is
-// successful, `tasklist:changed` is fired. The change can be canceled.
-//
-// jQuery is required.
-//
-// ### Methods
-//
-// `.taskList('enable')` or `.taskList()`
-//
-// Enables TaskList updates for the container.
-//
-// `.taskList('disable')`
-//
-// Disables TaskList updates for the container.
-//
-//# ### Events
-//
-// `tasklist:enabled`
-//
-// Fired when the TaskList is enabled.
-//
-// * **Synchronicity** Sync
-// * **Bubbles** Yes
-// * **Cancelable** No
-// * **Target** `.js-task-list-container`
-//
-// `tasklist:disabled`
-//
-// Fired when the TaskList is disabled.
-//
-// * **Synchronicity** Sync
-// * **Bubbles** Yes
-// * **Cancelable** No
-// * **Target** `.js-task-list-container`
-//
-// `tasklist:change`
-//
-// Fired before the TaskList item change takes affect.
-//
-// * **Synchronicity** Sync
-// * **Bubbles** Yes
-// * **Cancelable** Yes
-// * **Target** `.js-task-list-field`
-//
-// `tasklist:changed`
-//
-// Fired once the TaskList item change has taken affect.
-//
-// * **Synchronicity** Sync
-// * **Bubbles** Yes
-// * **Cancelable** No
-// * **Target** `.js-task-list-field`
-//
-// ### NOTE
-//
-// Task list checkboxes are rendered as disabled by default because rendered
-// user content is cached without regard for the viewer.
