 * @name Tab

 * <ion-tabs>
 * 	 <ion-tab tab-title="Home" tab-icon="home" [root]="tabOneRoot"></ion-tab>
 * 	 <ion-tab tab-title="Login" tab-icon="star" [root]="tabTwoRoot"></ion-tab>

 *
 * @description
 * _For basic Tabs usage, see the [Tabs section](../../../../components/#tabs)
 * of the Component docs._
 *
 * Tab components are basic navigation controllers used with Tabs.  Much like
 * Nav, they are a subclass of NavController and can be used to navigate
 * to pages in and manipulate the navigation stack of a particular tab.
 *
 * For more information on using navigation controllers like Tab or [Nav](../../nav/Nav/),
 * take a look at the [NavController API reference](../NavController/).
 *
 * See the [Tabs API reference](../Tabs/) for more details on configuring Tabs
 * and the TabBar.

 *
 * @property {any} [root] - set the root page for this tab
 * @property {any} [tab-title] - set the title of this tab
 * @property {any} [tab-icon] - set the icon for this tab
