[Mini-NDN] [Nfd-dev] General NFD status - reusing the functions to calculate CS PIT FIB entries

[Aman Maldar]

 Thank you Mr. Afanasyev,

write a tool that requests General Status Dataset from NFD

- This is exactly something I am looking for.

I tried following
mini-ndn >> a ndnping /localhost/nfd/status/general

Following is the log. The question is, I am new to this tlv mapping
concept. I read the link mentioned, but I am not able to understand how the
mapping is done,
Assume, I just want to get CS entries from response below? How do I do
that? or Please redirect me to reference/documentation. Sorry, may be this
is a rookie question.

1518402552.534222 DEBUG: [Forwarder] FWD onIncomingInterest face=277

Thank you again.
