[ndnSIM] Rocketfuel Topologies

[Alex Afanasyev]

There are simpler ways of working with rocketfuel topologies.  Check this old repository https://github.com/cawka/ndnSIM-sample-topologies <https://github.com/cawka/ndnSIM-sample-topologies>

It may not compile with the latest versions ndnSIM, but you can simply borrow the converted topologies.  See the readme regarding what has been changed/inferred in the topologies.
