[ndnSIM] Setting PIT size

Hi, Junxiao. Thanks for replying. To limit the PIT I put the following line
code in onInconmingInterest at forwarder.cpp:

if (m_pit.size() <= MAX_PIT_SIZE) {
  // Do the Interest pipeline process
} else
return;  // Drop interest

Is that a "correct" way to achieve a PIT limitation?
