Fixing the steering controller

Sadly, the steering controller problem was also the result of careless mistakes. Like the velocity calculation, the steering controller problem was the result of dividing by zero. When we were editing the subVIs that converted steering wheel angle to number of ticks of the encoder to make the type definitions all consistent, we had been careless and had not reset the constant that converted degrees to ticks to the correct default value. As such, the default value was left as zero instead of the correct value. Conseuquently, when we used that subVI to calculate desired steering wheel position in ticks (divide desired position in degrees by the constant), the resulting desired steering wheel position in ticks was always extremely large. As such, the steering wheel was always trying to turn to reach that very large number. 

The fix ended up being resetting that constant to the correct value and the steering controller seemed to behave normally again.
