Added Bluetooth-controlled Sejway and PC controller for this Sejway.
The program works as follows: Start BTSejway on the NXT an PCSejwayController on the computer. Once the NXT says "Waiting...", press Connect in the PC program and wait for the NXT to say Connected. Once this has been done, you can enter values for the 4 parameters and press Go and the Segway will start trying to balance. Pressing the grey button on the Segway stops the program, while pressing the orange button stops the Sejway from running and makes it wait for new parameter values.
