	Have fun...

	1> terrain [power [seed]]

	default power is 6 (2^6 = 64x64 grid)
	default seed is time(0L) (essentially random)
	^C or BREAK the CLI, or ^C/ESC in the screen to kill

	note: people w/ 512K amiga's can barely do a power of 7 max.

technical:

	This is a fractal terrain generator.  The generator uses a stateless
binary subdivision method.  That is, there is very little static state.  This
is accomplished by using guarenteed non-randomness for a specific point...
That is, after generating an initial seed, the random number generated for a
specific point is always the same for that point.  This is required for
continuity as edge overlap is the basis of the binary subdivision method.
