# life.py -- A curses-based version of Conway's Game of Life.
# Contributed by A.M. Kuchling <amk1@bigfoot.com>
#
# An empty board will be displayed, and the following commands are available:
# E : Erase the board
# R : Fill the board randomly
# S : Step for a single generation
# C : Update continuously until a key is struck
# Q : Quit
# Cursor keys : Move the cursor around the board
# Space or Enter : Toggle the contents of the cursor's position
#
# TODO :
# Support the mouse
# Use colour if available
# Make board updates faster

Attributes:
X,Y : horizontal and vertical size of the board

next generation. Then display the state

erase() -- clear the entire board
makeRandom() -- fill the board randomly
