title: how to add token auth to swagger + django rest framework?
body: <p>I am using both great tools <a href="http://www.django-rest-framework.org/">DRF</a> and <a href="http://github.com/marcgibbons/django-rest-swagger">Django-REST-Swagger</a>, however a few of my API views are under token authentication. </p>
  
  <p>So now I'd like to add to my swagger doc page of my API the possibility to test those token auth api urls, including the Token header. How could I do this?. </p>
  
  <p>A snapshot of my class API view is like this:</p>
  
  <pre><code>class BookList(APIView):
      """
      List all books, or create a new book.
      """
      authentication_classes = (TokenAuthentication, )
      permission_classes = (IsAuthenticated,)
      ...
  </code></pre>
  
  <p>Since Swagger auto detects a lot of stuff, I was expecting to notice about token auth, and ask me about token or user id in its web interface, but it doesn't. Hence I am testing it manually through CURL commands...</p>
