/**
 * \brief This is a dummy-class for testing reasons
 *
 * This class is just a dummy implementation for testing the
 * library-loading-mechanism and a few other concepts.
 * It is a sub-class of Widget and is going to be extended to
 * the "real" Button -class.
 *
 * The constructor loads a VRML-file and uses the inherited methods
 * for placing it at the right position. It also loads an animation for
 * pressing and releasing the button.
 *
 * The important factory-Methods, which are defined in the cpp-file, are:
 *
 *   <code>extern "C" Widget* _create_Button(XMLNode *xml) {</code>
 *   <code>   return new Button(xml);                       </code>
 *   <code>}                                                </code>
 *
 *   <code>extern "C" void _destroy_Button(Widget* w) {     </code>
 *   <code>  delete w;                                      </code>
 *   <code>}                                                </code>
 *
 * The word "Button" in the method-signatures has to be equal to the
 * classname!
