[ndnSIM] Issue with writing custom nametree

[Swetha B]

Hi all,
I am implementing NDN tables indexing using closed hashing with linear
probing in ndnSIM2.7.
To achieve that I modified name-tree-hashtable.cpp and
name-tree-iterator.cpp.
After modifications i am able to successfully run producer consumer
applications.
In my custom scenario i am accessing FIB table of a node to insert a prefix
and later execute consumer producer applications using that prefix.

auto& fib1 = node1->GetObject<ndn::L3Protocol>()->getForwarder()->getFib();
  auto e = fib1.insert(prefix).first;
  ndn::FibHelper::AddRoute(node1,prefix,node4,1);

When i execute this scenario i see that visualizer is'nt working and also
the regular setup FIB tables on nodes is'nt taking place. I have shared a
snapshot of execution.

Thanks.
