/**
 * @name NavParams
 * @description
 * NavParams are an object that exists on a page and can contain data for that particular view.
 * Similar to how data was pass to a view in V1 with `$stateParams`, NavParams offer a much more flexible
 * option with a simple `get` method.
 *
 * @usage
 * ```ts
 * import { NavParams } from 'ionic-angular';
 *
 * export class MyClass{
 *
 *  constructor(navParams: NavParams){
 *    // userParams is an object we have in our nav-parameters
 *    navParams.get('userParams');
 *  }
 *
 * }
 * ```
 * @demo /docs/demos/src/nav-params/
 * @see {@link /docs/components#navigation Navigation Component Docs}
 * @see {@link ../NavController/ NavController API Docs}
 * @see {@link /docs/api/components/nav/Nav/ Nav API Docs}
 * @see {@link /docs/api/components/nav/NavPush/ NavPush API Docs}
