(function($) {
 
/**
 * A page loading progress object. Initialized by passing a "loader" element in
 * which the loading progress will be displayed by a
 * <div><span>[dynamicPercentage]</span>%</div>
 *
 * e.g. Insert <div id="loader"></div> inside your page.tpl.php (or html...)
 *      then follow usage :)
 *
 * Usage:
 *    $('#loader').loader({options});
 *
 * Options:
 *    'wrapper': $(document.body),
 *        The element in which we check for the images to load
 *    'container': $('#container'),
 *        Container for your content which will get hidden then faded-in when
 *        the page has finished loading
 *    'loadingClass': 'loading',
 *        CSS class added to the loader and container for extra theming
 *    'callback': function(){}
 *        Callback function that gets called after $('#container') finished
 *        fading in
