    This program uses the HiLoGame class to play a number
    guessing game. It is provided as a driver to be used
    once the HiLoGame class has been implemented.
    
    Note: This class depends upon the presence of Keyboard.java
    (or Keyboard.class) in the same directory. Keyboard.java is
    provided on the course web site.
