Guessing for impossible puzzles where KeyCell fails:
.) pick cell with minimal # digits;
.) assert one of them;
.) use KeyCell to ramify;
	a) if result is a success, then done.
	b) if result is a failure, with some
		empty cells, or some houses missing digits,
		then UNDO & pick another digit.
	c) if result is inconclusive...recursively repeat
		the described process...
		This has only happened with "filmer".
