 *  Handles AJAX navigation events
 * 
 * Secondary navigation, loaded elements depend on page template of source and target pages
 * Template 1 = Landing page
 * Template 2 = Without photo slider, without right sidebar
 * Template 3 = Without photo slider, with right sidebar
 * Template 4 = With photo slider, without right sidebar
 * Template 5 = With photo slider, with right sidebar
 * 
 * Todo: 
 *      Show active subnavigation when url is manually inputted (or always redirect to template)
