paper: joystick sensitivity (gain) adjustment

[Roger]

Yesterday I gave this to one of my programmers to put into our LabVIEW code, as a sort of a warm-up exercise. An added bonus was making it a sub-vi to plug into future code.

There is a difference in driving, though perhaps not enough to change a good driver with careful joystick control. We didn't test it fully however.

A suggetion that simplifies changing "a" from rewriting code to letting the driver change it on the fly: use the thumb-thingie on the KOP joystick (it's at the base in the front and is known as axis3). It's range is -1 to +1, but with simple math can be converted to 0 to +1.
