/*
The mou.xx functions below are invoked as the onMouseOver and onMouseOut functions for any LI element in the
navigation bar that contains a drop-down sub menu.  These functions are needed for Internet Explorer previous to
version 7, as versions 6 and earlier did not support the ":hover" pseudoclass for LI elements.  The CSS rules that 
control the appearance and disappearance of the drop-down menus are sensitive to the appearance and disappearance of
the "underCursor" regular class as well as the ":hover" pseudoclass.
