// Feb 2009 - initial common JS contains ajaxGet for AJAX calls to rGet.asp
// as in: ajaxGet('ajax2', '{SiteLinkName}', 'Panel170')  

// 02/21/09 moved toggle, toggleTab and selectCat functions to from /site/togglerow.js to this common.js file
// 04/26/11 added Google Analytics for Regent Cruise Destinations
// 05/10/11 removed Google Analytics, code now resides in rsSites.IncludeHTMLHeader fields
