'''menu.py -- a simple menu-driven program

   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.
