Binds a control group to a DOM element.
# Example
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.
Here we use <a href='FormDirectives-var.html'><code>FormDirectives</code></a>, rather than importing each form directive individually, e.g.
`ControlDirective`, `ControlGroupDirective`. This is just a shorthand for the same end result.
```
@Component({selector: "login-comp"})
@View({
directives: [FormDirectives],
inline: "<form [control-group]='loginForm'>" +
"Login <input type='text' control='login'>" +
"Password <input type='password' control='password'>" +
"<button (click)="onLogin()">Login</button>" +
"</form>"
})
class LoginComp {
loginForm:ControlGroup;
constructor() {
this.loginForm = new ControlGroup({
login: new Control(""),
password: new Control("")
});
}
onLogin() {
// this.loginForm.value
}
}
