title: Where is Drupal Organic Group Role Data stored? How do I access it?
body: <p>I've created a custom Role for my Group. 
  I've assigned a user, who was a member of the Group, to this special Role.
  Now, I want to access a user's Role in the Group via PHP, but I can't find it anywhere.<br>
  I've pored over the Devels of both the User and Group.  I can access the fact that the user is a <em>member</em> of the group in the user's group_audience array, but not what their <em>role</em> is in that group.</p>
  
  <p>Any advice? </p>
