[ndnSIM] PIT Stats

[harshad shirwadkar]

Hello all,

I am trying to find out size of PIT periodically. It looks like
somebody had the same problem back in 2013 and it was possible to
track PIT size as PIT was implemented inside ndnSIM. Now, it looks
like ndnSIM uses NFD's PIT. I am not sure how can I track PIT size
now. How can I do that?

Thanks,
Harshad.
