FBLoginView is a custom UIView that renders a button to login or logout based on the
state of FBSession.activeSession
This view is closely associated with FBSession.activeSession
. Upon initialization,
it will attempt to open an active session without UI if the current active session is not open.
The FBLoginView instance also monitors for changes to the active session.
