//Change Log:
//* Updated: July 11th, 07: Fixed bug with persistence not working. Doh.
//* Updated: July 9th, 07: Added session only persistence to tabs (set "enabletabpersistence" var below). Only .js file changed.
//* Updated Nov 8th, 06. Ability to select a tab dynamically, by calling a method (ie: via a link). Only .js file changed.
