* Creates and binds a control group to a DOM element.
*
* This directive can only be used as a child of {@link NgForm} or {@link NgFormModel}.
*
* ### Example ([live demo](http://plnkr.co/edit/7EJ11uGeaggViYM6T5nq?p=preview))
*
* ```typescript
* @Component({
* selector: 'my-app',
* directives: [FORM_DIRECTIVES],
* template: `
* <div>
* <h2>Angular2 Control & ControlGroup Example</h2>
* <form #f="ngForm">
* <div ngControlGroup="name" #cg-name="form">
* <h3>Enter your name:</h3>
* <p>First: <input ngControl="first" required></p>
* <p>Middle: <input ngControl="middle"></p>
* <p>Last: <input ngControl="last" required></p>
* </div>
* <h3>Name value:</h3>
* <pre>{{valueOf(cgName)}}</pre>
* <p>Name is {{cgName?.control?.valid ? "valid" : "invalid"}}</p>
* <h3>What's your favorite food?</h3>
* <p><input ngControl="food"></p>
* <h3>Form value</h3>
* <pre>{{valueOf(f)}}</pre>
* </form>
* </div>
* `
* })
* export class App {
* valueOf(cg: NgControlGroup): string {
* if (cg.control == null) {
* return null;
* }
* return JSON.stringify(cg.control.value, null, 2);
* }
* }
* ```
*
* This example declares a control group for a user's name. The value and validation state of
* this group can be accessed separately from the overall form.
