//** Ajax Tabs Content script v2.0- © Dynamic Drive DHTML code library (http://www.dynamicdrive.com)



//** Updated Oct 21st, 07 to version 2.0. Contains numerous improvements



//** Updated Feb 18th, 08 to version 2.1: Adds a public "tabinstance.cycleit(dir)" method to cycle forward or backward between tabs dynamically. Only .js file changed from v2.0.



//** 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) 



//   -Modified Ajax routine so testing the script out locally in IE7 now works
