//  Cornell Extensions to Cocos2D
//
//  This module provides a polling interface for the Accelerometer.  Cocos2d decided
//  to make all of its input event-driven. This is a major problem, because it is hard
//  to associate the events with the current animation frame, potentially causing
//  lag.  A poller is an alternative input interface that allows us to query the
//  current state of the keyboard when we need it.
