[ndnSIM] How to obtain content diversity of network?

Getting the number of cached Data packets can be done something like this (I'm copying a part of examples/ndn-simple-with-cs-lfu.cc):

  uint64_t csCount = 0;
  for (NodeList::Iterator node = NodeList::Begin ();
       node != NodeList::End ();
       node ++)
      Ptr<ndn::ContentStore> cs = (*node)->GetObject<ndn::ContentStore> ();
      csCount += cs->GetSize ();

The total number of content in the network is something that is known just to you in your simulation scenario, so you can manually pre-calculate the value based on simulation setup.  (In general, number of content in the network is virtually unlimited.)
