//** All Levels Navigational Menu- (c) Dynamic Drive DHTML code library: http://www.dynamicdrive.com
//** Script Download/ instructions page: http://www.dynamicdrive.com/dynamicindex1/ddlevelsmenu/
//** Usage Terms: http://www.dynamicdrive.com/notice.htm

//** July 7th, 08'- Creation Date

//** July 16th, 08'- Updated to v 1.3:
	//1) Adds "Side Bar" orientation option. 
	//2) Drop Down Menus now auto adjust their positioning if too close to either right or bottom window edges.
	//3) Enhanced IFRAME shim "coverage" on the page.

//** July 19th, 08'- Updated to v 1.31: Drop down menu now positions at top of window edge if there's neither room downwards or upwards to settle.
//** Aug 13th, 08'- v1.32: Moved "rel" attribute from menu's <li> elements to inner <a>, for validation reasons

//** Sept 10th, 08'- Updated to v 1.4:
	//1) Added optional "sliding" animation when sub menus are revealed.
	//2) Arrow images now dynamically positioned, instead of relying on CSS's "right" property
