:markdown
  Creates and binds a control group to a DOM element.
  
  This directive can only be used as a child of <a href='NgForm-class.html'><code>NgForm</code></a> or <a href='NgFormModel-class.html'><code>NgFormModel</code></a>.
  
  # Example
  
  In this example, we create the credentials and personal control groups.
  We can work with each group separately: check its validity, get its value, listen to its changes.
  
   ```
  @Component({selector: "signup-comp"})
  @View({
       directives: [formDirectives],
       template: `
               <form #f="form" (submit)='onSignUp(f.value)'>
                 <div ng-control-group='credentials' #credentials="form">
                   Login <input type='text' ng-control='login'>
                   Password <input type='password' ng-control='password'>
                 </div>
                 <div *ng-if="!credentials.valid">Credentials are invalid</div>
  
                 <div ng-control-group='personal'>
                   Name <input type='text' ng-control='name'>
                 </div>
                 <button type='submit'>Sign Up!</button>
               </form>
       `})
  class SignupComp {
   onSignUp(value) {
     // value === {personal: {name: 'some name'},
     //  credentials: {login: 'some login', password: 'some password'}}
   }
  }
  
   ```
