A PSMoveClient will communicate with the PSMoveService via network protocols. To enable communication between clients and services running on different architectures (e.g. Windows-based service, arduino client), it is necessary to serialize the data before it is transmitted. We use Google Protocol Buffers to do the serialization. This requires that the messages be described using a custom syntax, then the associated classes are automatically generated by the protobuf compiler.

TODO: PSMoveProtocol.proto, add Tracker and HMD -related messages.
