title: Generic email validator
body: <p>I want to create a form where the user will enter his email. I'd like to validate email format client-side.</p>
  
  <p>Is there any generic email validator in Angular 2?</p>
  
  <p>NB: Something similar to <a href="https://docs.angularjs.org/api/ng/input/input%5Bemail%5D" rel="noreferrer">AngularJS validator</a>.</p>
