   * Binds an existing control group to a DOM element.
   *
   * ### Example ([live demo](http://plnkr.co/edit/jqrVirudY8anJxTMUjTP?p=preview))
   *
   * In this example, we bind the control group to the form element, and we bind the login and
   * password controls to the login and password elements.
   *
   *  ```typescript
   * @Component({
   *   selector: 'my-app',
   *   template: `
   *     <div>
   *       <h2>NgFormModel Example</h2>
   *       <form [ng-form-model]="loginForm">
   *         <p>Login: <input type="text" ng-control="login"></p>
   *         <p>Password: <input type="password" ng-control="password"></p>
   *       </form>
   *       <p>Value:</p>
   *       <pre>{{value}}</pre>
   *     </div>
   *   `,
   *   directives: [FORM_DIRECTIVES]
   * })
   * export class App {
   *   loginForm: ControlGroup;
   *
   *   constructor() {
   *     this.loginForm = new ControlGroup({
   *       login: new Control(""),
   *       password: new Control("")
   *     });
   *   }
   *
   *   get value(): string {
   *     return JSON.stringify(this.loginForm.value, null, 2);
   *   }
   * }
   *  ```
   *
   * We can also use ng-model to bind a domain model to the form.
   *
   *  ```typescript
   * @Component({
   *      selector: "login-comp",
   *      directives: [FORM_DIRECTIVES],
   *      template: `
   *        <form [ng-form-model]='loginForm'>
   *          Login <input type='text' ng-control='login' [(ng-model)]='credentials.login'>
   *          Password <input type='password' ng-control='password'
   *                          [(ng-model)]='credentials.password'>
   *          <button (click)="onLogin()">Login</button>
   *        </form>`
   *      })
   * class LoginComp {
   *  credentials: {login: string, password: string};
   *  loginForm: ControlGroup;
   *
   *  constructor() {
   *    this.loginForm = new ControlGroup({
   *      login: new Control(""),
   *      password: new Control("")
   *    });
   *  }
   *
   *  onLogin(): void {
   *    // this.credentials.login === 'some login'
   *    // this.credentials.password === 'some password'
   *  }
   * }
   *  ```
