	menu.py

    Jeff Ondich, 9 April 2009

    This program presents the user with a menu of options.
    After the person types a response, the program calls
    a function to perform the task the person selected.
    This is a small illustration of how to break a big
    problem (present a menu and act according to the user's
    selection) into a collection of smaller ones (print the menu,
    do each operation, etc.) using functions.
