/**
 * This class provide a almost-out-of-the-box wicket Panel with a smoothgallery
 * in it. What is missing are Mootools resources cause they should be added
 * outside the panel.
 * 
 * To add the Mootools javascript resources just make:
 * 
 * 
 *  add(JavascriptPackageResource.getHeaderContribution(WicketSlides.MOOTOOLS));
 *  add(JavascriptPackageResource.getHeaderContribution(WicketSlides.MOOTOOLS_MORE));
 * 
 * 
 * 
 * in a parent container of the SlidesPanel instance.
