The LIFE demo displays successive generation of Conway's "Game of Life"
on the graphics scope.

To run the demo, type
	.EX LIFE

The "life" universe is 192x256 pixels, with wrap-around enabled.

There are various compilation options, but the default is to run the
"r pentomino", which runs for quite a while before stabilizing.

A Control-C character should be typed to exit back to the dot prompt.
