Multicast IPv6 traffic support

by Krishna Teja Yadavalli for The ns-3 Network Simulator Project

As of now NS-3 is not supporting MLDv2 or PIM-SM. As a result of this we are setting up the routes manually . In real life nodes join and leave different multicast groups quite frequently and they also mention the sources in which they are interested in. By using this information there is lot of scope for optimization of the multicast traffic .My proposal is to make the NS-3 support to Multicast more realistic by implementing MLDv2 protocol.
