IMPORTANT: This method must be invoked at the top of the calling
activity's onActivityResult() function or Facebook authentication will
not function properly!

If your calling activity does not currently implement onActivityResult(),
you must implement it and include a call to this method if you intend to
use the authorize() method in this SDK.
