Attached is my code. It should be complete, but I need y'all to take a
look at it to see if you see anything wrong with it. I removed the
LObject class, since it seemed superfluous; the DHTObject class now
contains a vector< vector<unsigned char> >, instead of a vector<LObject>
(LObject only contained a vector< vector<unsigned char> >, so I figured
we were having an extra layer of vectors unnecessarily).
