Added config.h

config.h should be the only place for the pragma configurations. The
motor names will always be static across different files.
Format for mecanum algorithm

Added mecanumDrive.h, which contains just a basic form of the algorithm
to drive with mecanum wheels. The same algorithm should be copied into
an actual movement file later.
Added settings.h

settings.h is a header file containing all sorts of useful quantity
settings, such as speed limits, joystick defaults, and later, servo
positions and adjustments.
Added movement.h

movement.h should contain all methods related to moving the robot's
position on the field. Robot functions should be defined elsewhere.
Finished preliminary movement.h

The movement header file should now be complete to a preliminary state.
It has not been tested or debugged, but the main setMovement() function
is fully defined, besides for specific motors.
