[Mini-NDN] namespace scope

[sepehr abdous]

Thank you for your guide about advertise.

I still need to know the source of file in my simulation. In other words if
for instance 4 nodes have the file f, I need to know which one is sending
me the f.

I looked into nfd.log and nlsr.log but nothing seemed to be useful for me?
when I use ndncatchunks in node c, nothing written in nlsr.log and nfd.log
can be used to find the source of file?

any ideas?

Best,
Sepehr
