The Edit Class window has three menu items which appear at the top of the window. The first,
Save Class, is available at all times and is used to save any changes made on the Class Info
tab, or to add a class to the system. The other two are only active when you are editing a class.
Save Class: Saves the current class or adds a new class to the system.
Clone Class: Opens the clone class dialog box; the clone class function allow you to copy the
current class as a whole or to copy individual items to an existing course.
Add Items: Opens a blank Edit/New Item window and allows you to add an individual item
to the currently displayed course.
