#Brady Fisher
#A number guessing game.
#A random number between 0 and 99 is selected.
#Then players will take turns guessing the number.
#Can be played with Computer vs Computer, Human vs Computer, or Human vs Human.
#Where the computer randomly guesses a number between the high and low limits found by previous guesses.
