[ndnSIM] Debugging error

[Alex Afanasyev]

Unfortunately, you cannot do such things with C++... you created multiple duplicate compilation units.

For changes that are part of ndnSIM (changes in forwarder.cpp/hpp), you cannot use extensions in the scenario repo.  Extensions are for **additional** functionality or anything that can modify functionality within available APIs (separate strategies, processing, etc.).  If you are trying to do changes to the core, you would have to do it in the core itself.
