-track contact failures, last replied, and last requested. use this to provide a 'contact_is_good' property on Contact objects -ensure no duplicate contact objects are created -remove confusing conflation of node id strings with Contact objects, update docstrings -move RPC failure tracking to a callback/errback pair in sendRPC (so the contact is only updated once) -handle seed nodes during the join sequence by setting their node ids after they initially reply to our ping -name all of the kademlia RPC keyword args, remove confusing **kwargs and dictionary parsing -add host ip/port to DHT send/receive logging to make the results comprehensible when running many nodes at once
