1.5 MasterMinding: "master.ss"
The teachpack implements GUI for playing a simple master mind-like game, based on a function designed by a student. The player clicks on two colors and the program responds with an answer that indicates how many colors and places were correct.
Chooses two “secret” colors and then opens a graphical user interface for playing MasterMind. The player is prompted to choose two colors, via a choice tablet and mouse clicks. Once chosen, master uses check-guess to compare them.
If the two guesses completely match the two secret colors, check-guess must return 'PerfectGuess; otherwise it must return a different, informative symbol.
