[ndnSIM] The number of cache hit/miss and PIT entries per interface

[Amin Karami]

Hi Alex and ndnSIM users,
For evaluation of some methods, we need specific information such as the 
number of cache hit/miss and the number of PIT entries per interface in 
each time interval.

How is it possible with ndnSIM?

Thank you in advance for any help.
