   * @description
   *
   * The `<md-fab-toolbar>` directive is used present a toolbar of elements (usually `<md-button>`s)
   * for quick access to common actions when a floating action button is activated (via click or
   * keyboard navigation).
   *
   * You may also easily position the trigger by applying one one of the following classes to the
   * `<md-fab-toolbar>` 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.
   *
   * @usage
