# SL5. Conway's Game of Life

#Conway’s Game of Life. 

# http://en.wikipedia.org/wiki/Conway's_Game_of_Life

# We think this is a pretty cool game, so we want in, 
#and decide to implement it. But not implement it cowboy-style: 
#we know TDD! 
#and implement this funny game, step by step, with TDD.
