/*
 *  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.
