A GCGamepadSnapshot snapshot is a concrete GCGamepad implementation. It can be used directly in an
application to implement controller input replays. It is also returned as the result of polling
a controller.
The current snapshotData is readily available to access as NSData. A developer can serialize this to any
destination necessary using the NSData API.
The data contains some version of a GCGamepadSnapShotData structure.
