Tests for car is now done using the same abstraction as the main class
Updated the main activity to use vehicle and changed the name of the
thread classes.

Minor refactoring
Changed model server state to config to make it more generic

Also tested the change with all the values used
A broken version of the compiling fragment HUD
Refactored Fragment HUD and got it to work with the new changes

One of the big things is that we simplified the init functions and also
added setThrottle and setRoll to allow better handling for a car
Updated fragments to use correct namespacing
Renamed the plural namespaces to singular to bring it in line with all
the changes
ModelVehicle is no longer required and changed
