//** Animated Collapsible DIV v2.0- (c) Dynamic Drive DHTML code library: http://www.dynamicdrive.com.































//** May 24th, 08'- Script rewritten and updated to 2.0.































//** June 4th, 08'- Version 2.01: Bug fix to work with jquery 1.2.6 (which changed the way attr() behaves).































//** March 5th, 09'- Version 2.2, which adds the following:































			//1) ontoggle($, divobj, state) event that fires each time a DIV is expanded/collapsed, including when the page 1st loads































			//2) Ability to expand a DIV via a URL parameter string, ie: index.htm?expanddiv=jason or index.htm?expanddiv=jason,kelly































































//** March 9th, 09'- Version 2.2.1: Optimized ontoggle event handler slightly.
