title: Unity get facebook friend's name, score, and picture on leaderboard
body: <p>The FriendSmash sample is kind of hard to follow and i was wondering if anybody had just a simple way to retrieve these using the Unity Facebook SDK?</p>
  
  <p>Im pretty sure i have to use the QueryScores and ScoresCallback methods.
  Not sure how though.</p>
  
  <p>Basically i need a way to iterate through the list of friends and retrieve each of their names, scores, and profile pictures.</p>
  
  <p>Thank you!</p>
