David Smart / Mbed 2 deprecated GameOfLife

Conway's game of life applied to the mbed and an RA8875 LCD.

Dependencies:   LifeRules mbed RA8875

Inspired by a forum discussion on the mbed site, this version was scaled to support up to a 480x272 display - in a monochrome mode, or at a lower resolution in color (the color shows simple animation for birthing and dying cells).

Leveraging the LifeRules class, the game can be easily adapted to other displays - whether monochrome or color.

By default, this version allocates memory from the Ethernet ram banks, so avoids the memory limitations of some designs.

It should be simple to adapt it to any display - color or b&w, high or low resolution.
