/**
* @name Exposure
* @author Kristoffer Jelbring (kris@blogocracy.org)
* @version 0.2
*
* @type jQuery
* @cat plugins/Media
*
* @desc Turn a simple HTML list into a rich and smart photo viewer that handles very large amounts of photos.
*
* @example $('#images').exposure({options});
*
* @options
*	target:	(selector string) Where to insert the image being displayed. Defaults to '#exposure'. If no target is found, one will be created
* 	showThumbs:	(boolean) Display thumbnails or not. Defaults to true, but will be set to false if not thumbnails are found. 
*	showControls: (boolean) Display paging controls or not. Defaults to true, but will be set to false if missing controlsTarget.
*	showCaptions: (boolean) Display captions or not. Captions are added by setting a title attribute on the items in the list.
* 	showExtraData: (boolean) Display extra image data or not. This data is added by inserting inner HTML to the items in the list.
*	controlsTarget: (selector string) Where to insert the paging controls.
*	onThumb: (function) Callback function that is called when a thumbnail is displayed.
*	onImage: (function) Callback function that is called when an image is displayed.
*	onNext: (function) Callback function that is called when nextImage is called.
*	onPrev: (function) Callback function that is called when prevImage is called.
*	onPageChanged: (function) Callback function that is called when goToPage is called.
* 	loop: (boolean) Start over when last image is reached.
*	onEndOfLoop: (function) Callback function that is called when the last image is reached and loop option is set to false.
*	pageSize: (number) Maximum number of images (thumbnails) per page. Defaults to 5.
*	preloadBuffer: (number) Maximum number of images to keep in load queue at any given time. Defaults to 3.
*	keyboardNavigation: (boolean) Enable keyboard navigation.
*	clickingNavigation: (boolean) Enable browsing by clicking the image being shown.
*	onKeyDown: (function) Callback function to check if Exposure should catch the keydown event. Change to return false when focus is set a text input field.
