title: Extending component decorator with base class decorator
body: <p>I have several component decorator declarations that I repeat on every component, for example:</p>
  
  <pre><code>@Component({
      moduleId: module.id,
      directives: [BootstrapInputDirective]
  })
  </code></pre>
  
  <p>How can I apply these declarations to all my components? I tried to create a base class with this decorator and extend other classes with it but base class decorations doesn't seem to apply to derivative classes.</p>
