Issue 28 & 36 - encoders and decoders refactor This resolves #28 #36. This was on the story_61 branch, but I figured it may be helpful to push this into master/other branches before then. The main changes: - Moved encoding functions from RaceVisionByteEncoder into their own encoder classes. - Added a EncoderFactory and DecoderFactory, which return correct en/decoder based on MessageType. - All encoders implement MessageEncoder interface, and all decoder implement MessageDecoder interface. Extra changes: - Added names to most threads that are created. - Removed the nested while loop from MockOutput, and moved the XML stuff before the main loop (functionally it's the same).
