     * Purpose: To find the correct active page(s) and ensure they highlight properly *
     *                                                                                *
     * Revision 1.2: the script now only opens child elements, we have a clause in    *
     *               the header called noscript where it protects people without      *
     *               javascript                                                       *
     **********************************************************************************
     * Revision 1.1: adjust script to always default to open, thus ensuring if        *
     *               someone has no javascript or its disabled they still can         *
     *               navigate the site properly, and will only miss visual effects    *
     **********************************************************************************
     * Revision 1.0: create a script that detects left nav, and current url           *
