Added two Rexster services and a socket listener which, together, allow continuous queries (via SesameStream) and RDF streams similar to the Jade implementation of RDFAgents, but without using Jade.  The Extend-o-Hand gesture to Android/Brainstem to server/SesameStream to Android to audio signal path currently has a latency of 520ms.
Using AudioTrack/streaming rather than ToneGenerator cuts a whopping 300ms of latency
