 *   documentation updated
 *
 *   Revision 1.4.4.5  2006/01/03 13:18:51  fhesse
 *   cleaned up
 *   TODO: in the long run robot disappears (huge sensorvalues)
 *
 *   Revision 1.4.4.4  2006/01/03 10:01:46  fhesse
 *   moved to osg
 *
 *   Revision 1.4.4.3  2005/11/16 11:26:52  martius
 *   moved to selforg
 *
 *   Revision 1.4.4.2  2005/11/15 12:29:26  martius
 *   new selforg structure and OdeAgent, OdeRobot ...
 *
 *   Revision 1.4.4.1  2005/11/14 17:37:17  martius
 *   moved to selforg
 *
 *   Revision 1.4  2005/10/06 17:14:24  martius
 *   switched to stl lists
 *
 *   Revision 1.3  2005/09/22 12:24:36  martius
 *   removed global variables
 *   OdeHandle and GlobalData are used instead
 *   sensor prepared
 *
 *   Revision 1.2  2005/09/20 11:17:29  fhesse
 *   smaller changes, needs clean up and comments
 *
 *   Revision 1.1  2005/07/28 10:22:55  fhesse
 *   initial version,
 *   known bugs: when calling show params an
 *   "pure virtual function called" error  happens
 *
 *
 *                                                                 *
