/**
 * \@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>
 * ```
 *
 * ```ts
 * export class Tabs {
 *   constructor(public modalCtrl: ModalController) {
 *
 *   }
 *
 *   chat() {
 *     let modal = this.modalCtrl.create(ChatPage);
 *     modal.present();
 *   }
 * }
 * ```
