/**
 * @name Nav
 * @description
 *
 * `ion-nav` is the declarative component for a [NavController](../../../navigation/NavController/).
 *
 * For more information on using nav controllers like Nav or [Tab](../../Tabs/Tab/),
 * take a look at the [NavController API Docs](../../../navigation/NavController/).
 *
 *
 * @usage
 * You must set a root page to be loaded initially by any Nav you create, using
 * the 'root' property:
 *
 * ```ts
 * import { Component } from '@angular/core';
 * import { GettingStartedPage } from './getting-started';
 *
 * @Component({
 *   template: `<ion-nav [root]="root"></ion-nav>`
 * })
 * class MyApp {
 *   root = GettingStartedPage;
 *
 *   constructor(){
 *   }
 * }
 * ```
 *
 * @demo /docs/demos/src/navigation/
 * @see {@link /docs/components#navigation Navigation Component Docs}
