//** 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
