[Ndn-interest] Longest prefix matching in NDNPING

Hi John

`ndnpingserver /edu/ucla` registers route /edu/ucla/ping. It is not a
prefix of /edu/ucla/computerscience and hence will not match the Interest.
You may verify longest prefix match using ndnpoke tool, which registers the
same prefix as the argument.
Remember that ndnpoke requires the payload to be passed via stdin, and
quits after answering one Interest. See manpage for more information.

Yours, Junxiao
