 *   $Log: abstractwiring.h,v $
 *   Revision 1.8  2008/09/16 15:37:29  martius
 *   added randomgen
 *
 *   Revision 1.7  2008/04/28 11:14:54  guettler
 *   removed include "abstractrobot.h" (not needed)
 *
 *   Revision 1.6  2008/04/17 14:54:45  martius
 *   randomGen added, which is a random generator with long period and an
 *    internal state. Each Agent has an instance and passed it to the controller
 *    and the wiring. This is good for
 *   a) repeatability on agent basis,
 *   b) parallel execution as done in ode_robots
 *
 *   Revision 1.5  2007/11/07 13:40:24  martius
 *   sensors and motors also added as type here (not very nice anyway)
 *
 *   Revision 1.4  2006/12/21 11:44:17  martius
 *   commenting style for doxygen //< -> ///<
 *   FOREACH and FOREACHC are macros for collection iteration
 *
 *   Revision 1.3  2006/07/20 17:14:36  martius
 *   removed std namespace from matrix.h
 *   storable interface
 *   abstract model and invertablemodel as superclasses for networks
 *
 *   Revision 1.2  2006/07/14 12:24:02  martius
 *   selforg becomes HEAD
 *
 *   Revision 1.1.2.1  2005/11/16 11:24:27  martius
 *   moved to selforg
 *
 *   Revision 1.8  2005/11/09 13:55:44  martius
 *   *** empty log message ***
 *
 *   Revision 1.7  2005/10/24 09:52:36  fhesse
 *   comments in doxygen
 *
 *   Revision 1.6  2005/10/06 17:11:36  martius
 *   switched to stl lists
 *
 *   Revision 1.5  2005/08/03 20:34:58  martius
 *   use if Inspectable interface
 *
 *   Revision 1.4  2005/07/21 15:14:47  martius
 *   wireSensors and wireMotors get constant fields
 *
 *   Revision 1.3  2005/07/18 14:44:27  martius
 *   noise moved into wiring
 *
 *   Revision 1.2  2005/07/18 10:14:45  martius
 *   noise is added here
 *
 *   Revision 1.1  2005/07/14 15:57:53  fhesse
 *   now agent contains controller, robot and wiring, plotting ability included, therefore plotagent can be removed; ono2onewiring replaces one2oneagent
 *                                            *
 *                                                                         *
