/**
 * Very simple automatic image slideshow that degrades nice and is completely
 * unobtrusive. Simple to use, just apply to an image element by some selector:
 *
 *    <img src="start-image.jpg" alt="" id="my-image" />
 *
 *    $('#my-image').Slides({images : ['image1.jpg', 'image2.jpg']});
 *
 * This will create a slideshow that rotates over the images passed in the
 * array. You can also pass some optional settings for a bit of customization:
 *
 *    $('#my-image').Slides({
 *          images : [...], // required image URL array
 *            wait : 2000,  // wait before start, default 0
 *           pause : 5000,  // pause on each image, default 6000
 *            fade : 3000   // time to fade, default 1000
 *    });
 *
 * Passing these settings will create a slideshow that first waits 2s before
 * starting the slideshow timer. Each image is then displayed 5s and faded with
 * a transition time of 3s.
