[ndnSIM] Adding route manually

[Shahid Md. Asif Iqbal]

Dear Spyridon,
I have used the following steps to add route while operating in the
forwarder.cpp, but unfortunately the problem of timeout exists.

ns3::Ptr<ns3::Node> thisNode;
  thisNode = ns3::NodeList::GetNode(ns3::Simulator::GetContext());

  shared_ptr<Face> face =
const_pointer_cast<Face>(inFace.shared_from_this());

  ns3::ndn::FibHelper::AddRoute(thisNode, dataName, inFace.getId(), 0);

Thanks
Asif
