/*
 *  how this works:
 *  1. jQuery(window).hashchange(function(e){ .... });  detects any change in the url hash section. It needs the hashChange plugin.
 *  2. triggers the handleHashChange function
 *  3. the handlehashchange function reads the url get params and generates a new url, based on the hash + the ajax=1 parameter.
 *  (To test the result, just add &ajax=1 to any regular catalog url)
 *  4. the jquery.get function retrieves the ajax contents and updates the page contents.
 *  5. Any page can be called using just the function : loadAjaxProductsList(url,update_layered_navigation,update_compare_box,update_cart_box)
 *  Example:
 *      jQuery("a.link").click({
 *          loadAjaxProductsList( "http://www.mydomain.com/somepage.html?ajax=1" ,false,false,false);
 *      });
 *  That function should load the contents of http://www.mydomain.com/somepage.html in the col-main div (the central contents div)
 *
