This class will create a vertical cascading menu in HTML. The
and hiding of the sub-menus. The main menu is positioned statically
while the sub-menus are all positioned absolutely.
A cascading menu consists of the main menu and several choices.
Each choice may have sub-choices which will appear to the right
of the parent-choice. A menu may have as many choices as desired.
The width of each choice (and sub-choice) will be the width of the
menu Each choice (and sub-choice) can have as many children as
desired. The main menu and each choice object can be given its own
css class to control the style and appearence.
