[ndnSIM] Periodic tracing of CS

[Alex Afanasyev]

Hi André,

You can write something like this in your scenario:

    void
    printCsStats(Ptr<Node> node)
    {
      Ptr<ContentStore> cs = node->GetObject<ContentStore>();
    
      std::cout << Simulator::Now() << ", " << cs->GetSize() << std::endl;
    
      Simulator::Schedule(Seconds(5), &printCsStats, node);
    }
    
    ...
    
    Simulator::Schedule(Seconds(5), &printCsStats, node);

If you need per-prefix, then each time you have to enumerate all content items using Begin(), End(), and Next() ContentStore methods and calculate these stats before printing out.
