/**
* Creates and binds a control with a specified name to a DOM element.
*
* This directive can only be used as a child of {@link NgForm} or {@link NgFormModel}.
* ### Example
*
* In this example, we create the login and password controls.
* We can work with each control separately: check its validity, get its value, listen to its
* changes.
*
* ```
* @Component({
* selector: "login-comp",
* directives: [FORM_DIRECTIVES],
* template: `
* <form #f="ngForm" (submit)='onLogIn(f.value)'>
* Login <input type='text' ngControl='login' #l="form">
* <div *ngIf="!l.valid">Login is invalid</div>
*
* Password <input type='password' ngControl='password'>
* <button type='submit'>Log in!</button>
* </form>
* `})
* class LoginComp {
* onLogIn(value): void {
* // value === {login: 'some login', password: 'some password'}
* }
* }
* ```
*
* We can also use ngModel to bind a domain model to the form.
*
* ```
* @Component({
* selector: "login-comp",
* directives: [FORM_DIRECTIVES],
* template: `
* <form (submit)='onLogIn()'>
* Login <input type='text' ngControl='login' [(ngModel)]="credentials.login">
* Password <input type='password' ngControl='password'
* [(ngModel)]="credentials.password">
* <button type='submit'>Log in!</button>
* </form>
* `})
* class LoginComp {
* credentials: {login:string, password:string};
*
* onLogIn(): void {
* // this.credentials.login === "some login"
* // this.credentials.password === "some password"
* }
* }
* ```
