  ## Login [/v1/gamer/login]
  
  
  The login route is used to authenticate a gamer, and get basic profile information about him.
  
  Login for authenticated gamers will one of these : 
  
  * Facebook identity: use the `ID` and the `oauth token` from Facebook
  
  * Google+ identity: use the `ID` and the `oauth token` from Google+
  
  * RAW: use the `gamer_id` and the `gamer_secret` from a previous login
  
      Note: I've added RAW as a mean to login again, with gamer_id:secret
  
  After login has been called, HTTP Basic Authentication will be used to authenticate every requests.
