/**
  * @name FabContainer
  * @module ionic
  *
  * @description
  * `<ion-fab>` is not a FAB button by itself but a container that assist the fab button (`<button ion-fab>`) allowing it
  * to be placed in fixed position that does not scroll with the content. It is also used to implement "material design speed dial",
  * ie. a FAB buttons displays a small lists of related actions when clicked.
  *
  * @property [top] - Places the container on the top of the content
  * @property [bottom] - Places the container on the bottom  of the content
  * @property [left] - Places the container on the left
  * @property [right] - Places the container on the right
  * @property [middle] - Places the container on the middle vertically
  * @property [center] - Places the container on the center horizontally
  * @property [edge] - Used to place the container between the content and the header/footer
  *
  * @usage
  *
  * ```html
  * <!-- this fab is placed at top right -->
  * <ion-content>
  *  <ion-fab top right>
  *    <button ion-fab>Button</button>
  *  </ion-fab>
  *
  *  <!-- this fab is placed at the center of the content viewport -->
  *  <ion-fab center middle>
  *    <button ion-fab>Button</button>
  *  </ion-fab>
  * </ion-content>
  * ```
  *
  * Ionic's FAB also supports "material design's fab speed dial". It is a normal fab button
  * that shows a list of related actions when clicked.
  *
  * The same `ion-fab` container can contain several `ion-fab-list` with different side values:
  * `top`, `bottom`, `left` and `right`. For example, if you want to have a list of button that are
  * on the top of the main button, you should use `side="top"` and so on. By default, if side is ommited, `side="bottom"`.
  *
  * ```html
  * <ion-content>
  *  <!-- this fab is placed at bottom right -->
  *  <ion-fab bottom right >
  *    <button ion-fab>Share</button>
  *    <ion-fab-list side="top">
  *      <button ion-fab>Facebook</button>
  *      <button ion-fab>Twitter</button>
  *      <button ion-fab>Youtube</button>
  *    </ion-fab-list>
  *    <ion-fab-list side="left">
  *      <button ion-fab>Vimeo</button>
  *    </ion-fab-list>
  *  </ion-fab>
  * </ion-content>
  * ```
  *
  * A FAB speed dial can also be closed programatically.
  *
  * ```html
  * <ion-content>
  *  <ion-fab bottom right #fab>
  *    <button ion-fab>Share</button>
  *    <ion-fab-list side="top">
  *      <button ion-fab (click)="share('facebook', fab)">Facebook</button>
  *      <button ion-fab (click)="share('twitter', fab)">Twitter</button>
  *    </ion-fab-list>
  *  </ion-fab>
  * </ion-content>
  * ```
  *
  * ```ts
  * share(socialNet: string, fab: FabContainer) {
  *   fab.close();
  *   console.log("Sharing in", socialNet);
  * }
  * ```
