 * This is a simple and useless example of a MeshLab filter plugin.
 *
 * You can use this class as a base to start and coding your plugin!
 *
 * You can change the name of the class. Just be sure that the class
 * inherits from the QObject class (needed to make the plugin a Qt plugin)
 * and the FilterPlugin class.
 *
 * Check the cpp file for the explanation of each member function of the class and
 * whether they are mandatory to be implemented.
