Moved Region and Path handling into its own roadrunner/ext folder. Moved data structures back into RoadRunnerService. Cleaned up Handler factories, used a map for fast lookup.
MessageHandler is now a generic class, instead of an Abstract + Android version.
Moved serialization code into its own class. Added a note on what to change next.
Removed two unused classes (from an earlier synchronization method). Removed supporting code in the Broker.
