#! The Game of Life is a cellular automaton devised by Dr. John Conway in 1970.

#* The rules of life:
#* 1. Any live cell with fewer than two live neighbours dies, as if by needs
#* caused by underpopulation.
#* 2. Any live cell with more than three live neighbours dies, as if by overcrowding.
#* 3. Any live cell with two or three live neighbours lives, unchanged, to the next
#* generation.
#* 4. Any dead cell with exactly three live neighbours cells will come to life.
