title: How to use Angular 2 (or 4) framework from CDN
body: <p>In Angular 1.x we had the option of linking to Angular framework using a CDN (<a href="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.0/angular.min.js" rel="noreferrer">https://ajax.googleapis.com/ajax/libs/angularjs/1.4.0/angular.min.js</a>).  Is that option available in Angular 2?</p>
