+John Conway's Game of Life
+
+The Rules
+---------
+The Game of Life was invented by John Conway (as you might have gathered).
+The game is played on a field of cells, each of which has eight neighbors (adjacent cells).
+A cell is either occupied (by an organism) or not.
+The rules for deriving a generation from the previous one are these:
+
+Survival
+--------
+If an occupied cell has 2 or 3 neighbors, the organism survives to the next generation.
+
+Death
+-----
+If an occupied cell has 0, 1, 4, 5, 6, 7, or 8 occupied neighbors, the organism dies
+(0, 1: of loneliness; 4 thru 8: of overcrowding).
+
+Birth
+-----
+If an unoccupied cell has 3 occupied neighbors, it becomes occupied.
