/*         Nested list collapsing script written by Mark Wilton-Jones - 21/11/2003 */
/* Version 2.2.0 - this script takes existing HTML nested UL or OL lists, and collapses them */
/*             Updated 13/02/2004 to allow links in root of expanding branch */
/*                   Updated 09/09/2004 to allow state to be saved */
/*           Updated 07/10/2004 to allow page address links to be highlighted */
/* Updated 28/11/2004 to allow you to force expand/collapse links to use just the extraHTML */
