//** Tab Content script v2.0- � Dynamic Drive DHTML code library (http://www.dynamicdrive.com)
//** Updated Oct 7th, 07 to version 2.0. Contains numerous improvements:
//   -Added Auto Mode: Script auto rotates the tabs based on an interval, until a tab is explicitly selected
//   -Ability to expand/contract arbitrary DIVs on the page as the tabbed content is expanded/ contracted
//   -Ability to dynamically select a tab either based on its position within its peers, or its ID attribute (give the target tab one 1st)
//   -Ability to set where the CSS classname "selected" get assigned- either to the target tab's link ("A"), or its parent container
//** Updated Feb 18th, 08 to version 2.1: Adds a "tabinstance.cycleit(dir)" method to cycle forward or backward between tabs dynamically
//** Updated April 8th, 08 to version 2.2: Adds support for expanding a tab using a URL parameter (ie: http://mysite.com/tabcontent.htm?tabinterfaceid=0)

//** 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.
//** July 3rd, 09'- Version 2.4, which adds the following:
			//1) You can now insert rel="expand[divid] | collapse[divid] | toggle[divid]" inside arbitrary links to act as DIV togglers
			//2) For image toggler links, you can insert the attributes "data-openimage" and "data-closedimage" to update its image based on the DIV state
