This program implements the game of Mastermind. Either the user or the
program tries to break a hidden color code, consisting of the colors
black, blue, red, green, yellow, white. The results of a guess (black: a
color is at the right position; or white: a color occurs in the code)
are internally represented as successors of 0. This could be extended to
handle integers. When the program is making guesses, it uses a simple
but powerful generate-and-test procedure is used, where the scores for
previous attempts are used as the test criterion.
