-# 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.
