rendezvous-socket 0.0.2

Using the help of a known publically routable [rendezvous-server](https://github.com/mikehale/rendezvous-server) endpoint establish a peer to peer connection between clients which may be behind NAT firewalls. In the event that NAT traversal techniques are not successful fallback to relaying the connection through the rendezvous server. All connections are SSL encrypted. Sessions are managed by the server.
