        /** This "software driver" implements the communication protocol for interfacing a Ibeo Lux laser scanners through an ethernet controller.
          *   This class does not need to be bind, i.e. you do not need to call C2DRangeFinderAbstract::bindIO.
          *   Connection is established when user call the turnOn() method. You can pass to the class's constructor the Lux's ip address and port.
          *   Device will NOT be configured. Configuration has to be done seperately.
          *
          * To get a laser scan you must proceed like that :
          * \code
          *     CIbeoLuxETH laser(string("192.168.0.10"), 1234);
          *     laser.turnOn();
          *     bool isOutObs, hardwareError;
          *     CObservation2DRangeScan outObs;
          *     laser.doProcessSimple(isOutObs, outObs, hardwareError);
          * \endcode
