replaced CHECK_EQUAL with BYTE_EQUAL in unit tests for routing table (conversion errors from size_type to string type)
added a test stub for class OMNeTStochasticForwardingPolicy
added parameter support (by means of NED files) in class OMNeTARAClient
added two parameters to the OMNeTARAClient NED file (RandomNetwork.ned) and added parameter support to the corresponding class
a runtime exception is now thrown if the forwarding policy is unknown
