"""
This is a twist on the number guessing game. In this version, the user thinks
of a number, and the computer tries to guess it. There is a trap. If the user
tries to cheat and keep telling the computer the number is higher or lower, and
it runs out of guesses (high == low), it prints that number out and exits.
