 * \brief This is a UDP implementation of dataIO_cluster..
 * 
 * This class uses UDP to fullfil the functions of dataIO_cluster.
 * It sends the clusterdata via UDP Broadcast into the network to any listening client.
 * 
 * 
 * \todo Add getHorizonColor to transport it to slave for consistent fog.
