/**
* @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();
* }
* }
* ```
