/**
 * Galleria (http://monc.se/kitchen)
 *
 * Galleria is a javascript image gallery written in jQuery. 
 * It loads the images one by one from an unordered list and displays thumbnails when each image is loaded. 
 * It will create thumbnails for you if you choose so, scaled or unscaled, 
 * centered and cropped inside a fixed thumbnail box defined by CSS.
 * 
 * The core of Galleria lies in it's smart preloading behaviour, snappiness and the fresh absence 
 * of obtrusive design elements. Use it as a foundation for your custom styled image gallery.
 *
 * MAJOR CHANGES v.FROM 0.9
 * Galleria now features a useful history extension, enabling back button and bookmarking for each image.
 * The main image is no longer stored inside each list item, instead it is placed inside a container
 * onImage and onThumb functions lets you customize the behaviours of the images on the site
 *
 * Tested in Safari 3, Firefox 2, MSIE 6, MSIE 7, Opera 9
 * 
 * Version 1.0

 * @author David Hellsing

 * @name Galleria
 * @type jQuery
 *
 * @cat plugins/Media
 * 
 * @example $('ul.gallery').galleria({options});
 * @desc Create a a gallery from an unordered list of images with thumbnails
 * @options
 *   insert:   (selector string) by default, Galleria will create a container div before your ul that holds the image.
 *             You can, however, specify a selector where the image will be placed instead (f.ex '#main_img')
 *   history:  Boolean for setting the history object in action with enabled back button, bookmarking etc.
 *   onImage:  (function) a function that gets fired when the image is displayed and brings the jQuery image object.
 *             You can use it to add click functionality and effects.
 *             f.ex onImage(image) { image.css('display','none').fadeIn(); } will fadeIn each image that is displayed
 *   onThumb:  (function) a function that gets fired when the thumbnail is displayed and brings the jQuery thumb object.
 *             Works the same as onImage except it targets the thumbnail after it's loaded.
