/**
 * @xmlimageflow
 *
 * XMLImageFlow is a jQuery plugin created by Esteban Acevedo / Y2K Services, Inc. / Next Horizon
 * This plugin will create a dynamic image gallery based on a list of images or an XML list of images.
 * The image gallery will look like a 3D carrousel where images will rotate left and right as if they 
 * were over a rotating platform.
 * Keep in mind that this plugin will only work for images that share the same dimensions.  If images with
 * different dimensions are used, clipping will occur.
 * Reflection is not supported.  If you want to give your gallery a reflection effect then you need to add 
 * the reflection manually to the image using any image manipulation software.
 *
 * Depends on:
 * 1) jquery-1.4.2.min.js
 * 2) jquery.easing.1.3.js
 * 3) jquery.mousewheel.js
 *
 * Usage:
 * 1) Include this source file in an html page via
 *    <script type="text/javascript" src="/path/to/xmlimageflow.js"></script>
 *    Make sure you call this js file after all other dependency files have been called.
 *	  i.e.
 *    <script type="text/javascript" src="js/jquery-1.4.2.min.js"></script>
 *    <script type="text/javascript" src="js/jquery.easing.1.3.js"></script>
 *    <script type="text/javascript" src="js/jquery.mousewheel.js"></script>
 *    <script type="text/javascript" src="js/xmlimageflow.js"></script>
 *	
 * 2) In your page script section or your custom actions js file add the following
 *    initialization line: var yourglobalhandler = $("yourselector").xmlimageflow();
 * 3) You can pass your own options: i.e. $("#xif").xmlimageflow({width:'300px',height:'100px'});
 *	  Default Options:
 * 	  		width: '100%', //Width of the XMLImageFlow object frame.  Can be any CSS value. -String
 *			height: '800px', //Height of the XMLImageFlow object frame.  Can be any CSS value. -String
 *			imageWidth: 415, //Width of the images.  -Integer
 *			imageHeight: 700, //Height of the images.  -Integer
 *			loadFromXML: false, //Flag to indicate of the image data should be loaded from an external XML file.  -Boolean
 *			dataSource: '', //URL of the XML file.  String
 *			startImage: 4, //Which image to show on load.  Should be ((numSectors + 1) / 2). -Integer.
 *			numSectors: 7, //Should always be an odd value starting from 3.  -Integer.
 *			speed: 50, //Animation duration of the glide effect. -Integer.
 *			webImageFolder: 'img/', //Folder where all the web ready images are stored. Must include the / at the end. -String.
 *			webImageExt: '.png', //File Type of all web ready images. Must include the dot.  Must be lowercase. -String.
 *			posterFolder: 'poster/', //Folder where all the original images are stored. Must include the / at the end. -String.
 *			posterExt: '.pdf', //File Type of all original images. Must include the dot.  Must be lowercase. -String.
 *			totalFieldID: '', //ID of the span that will be used to display the total.
 *			overlayID: '' //ID of the DIV containing the overlay HTML for the focused image on mouse over. -String.
 *			overlayImage: '' //File path of the image to use instead of the overlay div color. -String.
 * 4) You can bind any XMLImageFlow commands to your controls.  i.e. yourglobalhandler.moveLeft();
 *    will cause the carousel to glide to the left.
 *
 * Markup:
 * 1) If the images are not stored in an external XML file use this markup
 * <div id="xif" class="xif">
 *    <div class="xif-image"><p>imagepath/imagename1.ext</p><p>Keywords</p></div>
 *    <div class="xif-image"><p>imagepath/imagename2.ext</p><p>Keywords</p></div>
 * </div>
 *
 * 2) If the images are stored in an external XML file use this markup
 * <div id="xif" class="xif"></div>
 * 
 * Special Thanks And Recognition:
 * Inspired on the original ImageFlow by Finn Rudolph
 *
 * This solution is known as the Cover Flow technique, which has been developed by the artist 
 * Andrew Coulter Enright. Now - after it has been bought by Apple - it is used in 
 * iTunes and the file browser of Apples OSX.
 *
 * Special thanks to John O. Eze and Brett Callaghan for their ideas, suggestions
 * and troubleshooting!
 *
