Classifier/Multicast instproc new-group { src group iface code}

This method called when a new multicast group/source pair is seen by the underlying classifier/mcast object. We install a hash for the pair mapping it to a slot number in the classifier table and point the slot at a replicator object that sends each packet along the RPF tree.
