title: Accessing Google docs from a chrome extension
body: <p>I know that the Google Drive API allows for drive integration with Chrome Apps, but what about extensions? Can/How do I use the Drive API in a chrome extension? For example I want an extension that will have a popup that list a user's docs, how do I get access to their drive box?
  I know it starts with authentication, but I'm not sure how to do that either.</p>
