title: angular2 component styleUrls not working correctly
body: <p>I have an angular2 component:</p>
  
  <pre><code>@Component({
      providers: [
          FlowsheetService,
          SubscriptionService
      ],
      moduleId: module.id,
      selector: 'flowsheet',
      templateUrl: './flowsheet.component.html',
      styleUrls: ['./lastRow.css']
  })
  </code></pre>
  
  <p>lastRow.css in the same directory as the component file contains:</p>
  
  <pre><code>.yellow {
      background-color: yellow;
  }
  </code></pre>
  
  <p>in my third party control there is an API that needs a css class name as return value.</p>
  
  <p>that function is as follows:</p>
  
  <pre><code>function className() {
      return 'yellow';
  }
  </code></pre>
  
  <p>I don't see anywhere showing up in yellow in my 3rd party control.</p>
  
  <p>Am I coding this correctly in general?</p>
