/****
 *
 * Class ScheduleMenu is the pulldown menu view of the <a href =
 * "Schedule.html" Schedule </a> model class.  The first four items of the menu
 * correspond to the public Schedule methods.  The last item corresponds to the
 * Categories component of Schedule, which is the editable list of scheduled
 * item categories.
 *                                                                          <p>
 * The four items that correspond to methods each launch a method input dialog.
 * The last menu item, that corresponds to the categories list, launches a
 * non-modal category editing dialog.
 *                                                                          <p>
 * In terms of Java Swing components, the ScheduleMenu widget is a Java JMenu.
 * Anonymous instances of JMenuItem are defined for each menu item.  Details of
 * the dialog structures are given in their respective class definitions.
