+   *
+   * @description
+   * The `<md-fab-speed-dial>` directive is used to present a series of popup elements (usually
+   * `<md-button>`s) for quick access to common actions.
+   *
+   * There are currently two animations available by applying one of the following classes to
+   * the component:
+   *
+   *  - `md-fling` - The speed dial items appear from underneath the trigger and move into their
+   *    appropriate positions.
+   *  - `md-scale` - The speed dial items appear in their proper places by scaling from 0% to 100%.
+   *
+   * You may also easily position the trigger by applying one one of the following classes to the
+   * `<md-fab-speed-dial>` element:
+   *  - `md-fab-top-left`
+   *  - `md-fab-top-right`
+   *  - `md-fab-bottom-left`
+   *  - `md-fab-bottom-right`
+   *
+   * These CSS classes use `position: absolute`, so you need to ensure that the container element
+   * also uses `position: absolute` or `position: relative` in order for them to work.
+   *
+   * Additionally, you may use the standard `ng-mouseenter` and `ng-mouseleave` directives to
+   * open or close the speed dial. However, if you wish to allow users to hover over the empty
+   * space where the actions will appear, you must also add the `md-hover-full` class to the speed
+   * dial element. Without this, the hover effect will only occur on top of the trigger.
+   *
+   * See the demos for more information.
+   *
+   * ## Troubleshooting
+   *
+   * If your speed dial shows the closing animation upon launch, you may need to use `ng-cloak` on
+   * the parent container to ensure that it is only visible once ready. We have plans to remove this
+   * necessity in the future.
