//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.

var bustcachevar=1 //bust potential caching of external pages after initial request? (1=yes, 0=no)
var loadstatustext="";
var enabletabpersistence=0 //enable tab persistence via session only cookies, so selected tab is remembered (1=yes, 0=no)?
