#   Pizza
#   -----
#   This program is a pizza ordering program.
# 
#   It creates a window, several fields for typing in your name,
#   and several checkboxes and radio buttons for choosing what
#   you want on the pizza. Having filled in all the information,
#   a "place order" button will print out the order and exit the
#   the program. A "reset form" button empties the fields and
#   sets the program back to its inital state.
