	=item %primary_sub_menu

	The keys of this hash reference are the names of items in the primary_menu array
	which have sub-menus. For each key, the corresponding value is a reference to
	an array containing components extracted from lines in mydesk.tab which begin
	with primsub:.

=item show_return_link()	=item create_submenu()

	Creates XHTML for unordered list of sub-menu items which belong to a
	particular top-level menu item. Uses hover pseudo class in css to display
	dropdown list when mouse hovers over top-level item. Support for IE6
	(no hover psuedo class) via LC_hoverable class for <li> tag for top-
	level item, which employs jQuery to handle behavior on mouseover.

	Inputs: 4 - (a) link and (b) target for anchor href in top level item,
	(c) title for text wrapped by anchor tag in top level item.
	(d) reference to array of arrays of sub-menu items.
