* 
* @brief  code information
* The code is written with numerous start and end positions of code class.
* This made debugging much easier and will be used as a standard of practice 
* for future work.

* @author Jeremy Ogus
*
* @version 1.2.2
*
* @date 10/05/2015
*
*
*v1.0 - broken code in separate loops
*v1.1 - main game in working fashion, no bugs
*v1.2 - power saving and multi directional joystick included, 8 way
*v1.2.1 - pause system now flawless
*v1.2.2 - harder game, borders more efficient
