/**
 * @name Nav
 * @description
 * _For a quick walkthrough of navigation in Ionic, check out the
 * [Navigation section](../../../../components/#navigation) of the Component
 * docs._
 *
 * Nav is a basic navigation controller component.  As a subclass of NavController
 * you use it to navigate to pages in your app and manipulate the navigation stack.
 * Nav automatically animates transitions between pages for you.
 *
 * For more information on using navigation controllers like Nav or [Tab](../../Tabs/Tab/),
 * take a look at the [NavController API Docs](../NavController/).
 *
 * You must set a root page to be loaded initially by any Nav you create, using
 * the 'root' property:
 *
 * @usage
 * ```ts
 * import {Component} from '@angular/core';
 * import {ionicBootstrap} from 'ionic-angular';
 * import {GettingStartedPage} from './getting-started';
 *
 * @Component({
 *   template: `<ion-nav [root]="root"></ion-nav>`
 * })
 * class MyApp {
 *   root = GettingStartedPage;
 * }
 *
 * ionicBootstrap(MyApp);
 * ```
 *
 * ### Back Navigation
 *
 * If a [page](../NavController/#creating_pages) you navigate to has a [NavBar](../NavBar/),
 * Nav will automatically add a back button to it if there is a page
 * before the one you are navigating to in the navigation stack.
 *
 * Additionally, specifying the `swipeBackEnabled` property will allow you to
 * swipe to go back:
 * ```html
 * <ion-nav swipeBackEnabled="false" [root]="rootPage"></ion-nav>
 * ```
 *
 * Here is a diagram of how Nav animates smoothly between pages:
