       * \@name Tab
       * \@description
       * The Tab component, written `<ion-tab>`, is styled based on the mode and should
       * be used in conjunction with the [Tabs](../Tabs/) component.
       *
       * Each `ion-tab` is a declarative component for a [NavController](../../../navigation/NavController/).
       * Basically, each tab is a `NavController`. For more information on using
       * navigation controllers take a look at the [NavController API Docs](../../../navigation/NavController/).
       *
       * See the [Tabs API Docs](../Tabs/) for more details on configuring Tabs.
       *
       * \@usage
       *
       * To add a basic tab, you can use the following markup where the `root` property
       * is the page you want to load for that tab, `tabTitle` is the optional text to
       * display on the tab, and `tabIcon` is the optional [icon](../../icon/Icon/).
       *
       * ```html
       * <ion-tabs>
       *  <ion-tab [root]="chatRoot" tabTitle="Chat" tabIcon="chat"></ion-tab>
       * </ion-tabs>
       * ```
       *
       * Then, in your class you can set `chatRoot` to an imported class:
       *
       * ```ts
       * import { ChatPage } from '../chat/chat';
       *
       * export class Tabs {
       *   // here we'll set the property of chatRoot to
       *   // the imported class of ChatPage
       *   chatRoot = ChatPage;
       *
       *   constructor() {
       *
       *   }
       * }
       * ```
       *
       * You can also pass some parameters to the root page of the tab through
       * `rootParams`. Below we pass `chatParams` to the Chat tab:
       *
       * ```html
       * <ion-tabs>
       *  <ion-tab [root]="chatRoot" [rootParams]="chatParams" tabTitle="Chat" tabIcon="chat"></ion-tab>
       * </ion-tabs>
       * ```
       *
       * ```ts
       * export class Tabs {
       *   chatRoot = ChatPage;
       *
       *   // set some user information on chatParams
       *   chatParams = {
       *     user1: 'admin',
       *     user2: 'ionic'
       *   };
       *
       *   constructor() {
       *
       *   }
       * }
       * ```
       *
       * And in `ChatPage` you can get the data from `NavParams`:
       *
       * ```ts
       * export class ChatPage {
       *   constructor(navParams: NavParams) {
       *     console.log('Passed params', navParams.data);
       *   }
       * }
       * ```
       *
       * Sometimes you may want to call a method instead of navigating to a new
       * page. You can use the `(ionSelect)` event to call a method on your class when
       * the tab is selected. Below is an example of presenting a modal from one of
       * the tabs.
       *
       * ```html
       * <ion-tabs>
       *   <ion-tab (ionSelect)="chat()" tabTitle="Show Modal"></ion-tab>
       * </ion-tabs>pop
       * ```
       *
       * ```ts
       * export class Tabs {
       *   constructor(public modalCtrl: ModalController) {
       *
       *   }
       *
       *   chat() {
       *     let modal = this.modalCtrl.create(ChatPage);
       *     modal.present();
       *   }
       * }
       * ```
