/* 
Version : 0.2b
Last update : 22 october 2004

HISTORY

0.1b : first beta relase
0.2b :
	* Two new methodes have been added to anchor and span objects, highlighParents and unhighlightparents.
	* There is a new option to request the highlight of the parents of the selected entry. New option name : trackParents
	* The CSS class a.expand is now added to a node when it's expanded.
	* The CSS class a.breadcrumb is now added to the parents of the selected entry if the option trackParents is set to true;

KNOWN ISSUES
	* Overlay of select form object is not implemented.
	* Vertical positioning of absolute ul are not well understand by IE but correctly set in Mozilla in popup mode.
	* Horizontal positioning of absolute ul are not well understand by IE but correctly set in Mozilla in horizontal mode.
	* When icons are used with node, where is a layout problem in case the font size is too small.
	* The mouseover event seems to be slown down for unknown reason.
	* LI separators have an unexpected extra line with IE
	* Transparency is only working at level 1 with IE, but is working fine on every level with Mozilla
	* Popup UL positioning is currently not tested to be sure the UL is not displayed out of the visible area.
