 *
 * Call this function on an element that contains 
 * "panels" which, in turn, contain anchors. The container
 * element should contain ONLY related panels, as this plugin
 * will show only one first-child element of the container at once.
 *
 * Options:
 *
 *   showFn: function to show the current panel
 *   hideFn: function to hide the current panel's siblings
 *   nav: selector for the page's navigation 
 *   currentNavFn: function to run on the link in the nav
 *               that is associated with the anchor
 *   anchorClass: class assigned to anchor tags; setting this will
 *                improve the speed on pages with lots of links
 *   noAnchorFn: function to run if the URL does not contain an anchor
 *
 * See below for default option values. See the URL above for 
 * detailed documentation.
