mini-ndn

Currently in Mini-NDN, an nfd.conf file, which is used to set up each NFD process in the topology, is included in the repository. But, since the format of the nfd.conf file has changed for NFD, the configuration file included with Mini-NDN does not work with the current NFD repo HEAD.

Instead of including the nfd.conf file with Mini-NDN, the nfd.conf.sample file installed with NFD should be copied into the mini-ndn install directory and used to set up the NFD processes in Mini-NDN. This allows a user to use Mini-NDN with whichever version of NFD is currently installed and does not prevent backwards compatibility.
