Fixed DirectionVector addition code, it now adds DirectionVectors properly. Added a delay between updates of position, ParsableDouble so the resolution of the positioning system can be changed on the fly. Only thing left to do for positioning system is to calculate the rate of movement using either an accelerometer or encoders (preferably encoders because the accelerometer was being troublesome on Saturday Jan 26). Once encoders or accelerometer is added, must be tested.

THe PositioningSubsystem already has SendableDoubles that constantly update the WebServer with new values of x and y.
