  /**
   * If `NgForm` is bound in a component, `<form>` elements in that component will be
   * upgraded to use the Angular form system.
   *
   *##Typical Use
   *
   * Include `FORM_DIRECTIVES` in the `directives` section of a {@link View} annotation
   * to use `NgForm` and its associated controls.
   *
   *##Structure
   *
   * An Angular form is a collection of `Control`s in some hierarchy.
   * `Control`s can be at the top level or can be organized in `ControlGroup`s
   * or `ControlArray`s. This hierarchy is reflected in the form's `value`, a
   * JSON object that mirrors the form structure.
   *
   *##Submission
   *
   * The `ng-submit` event signals when the user triggers a form submission.
   *
   * ### Example ([live demo](http://plnkr.co/edit/ltdgYj4P0iY64AR71EpL?p=preview))
   *
   *  ```typescript
   * @Component({
   *   selector: 'my-app',
   *   template: `
   *     <div>
   *       <p>Submit the form to see the data object Angular builds</p>
   *       <h2>NgForm demo</h2>
   *       <form #f="form" (ng-submit)="onSubmit(f.value)">
   *         <h3>Control group: credentials</h3>
   *         <div ng-control-group="credentials">
   *           <p>Login: <input type="text" ng-control="login"></p>
   *           <p>Password: <input type="password" ng-control="password"></p>
   *         </div>
   *         <h3>Control group: person</h3>
   *         <div ng-control-group="person">
   *           <p>First name: <input type="text" ng-control="firstName"></p>
   *           <p>Last name: <input type="text" ng-control="lastName"></p>
   *         </div>
   *         <button type="submit">Submit Form</button>
   *       <p>Form data submitted:</p>
   *       </form>
   *       <pre>{{data}}</pre>
   *     </div>
   * `,
   *   directives: [CORE_DIRECTIVES, FORM_DIRECTIVES]
   * })

   *   constructor() {}

   *
   *   onSubmit(data) {
   *     this.data = JSON.stringify(data, null, 2);
   *   }
