Read Me About GKAuthentication
===========================================================================
GKAuthentication is a sample application that shows how to correctly 
submit an Achievement and view the GKAchievementViewController. 
This code is completely copy and paste-able.
 
It is important to note that there is no code for locally saving the state 
of the achievements submitted. GKAchievementViewController will present the
highest completion that has been submitted.
 
IMPORTANT: When adding support for Game Center to an application, it is not
enough to simply add the necessary code to your application.  You also
need to configure your app in iTunes Connect to match your desired
configuration.
