coordinate system question #12

Awesome package, thanks!!

Pacejka defines the slip such that a positive slip angle produces a positive lateral force, but running the examples in this package, the opposite is true.

Looks like Pacejka has z down as positive, so Fz would be a negative scalar. If use this, then I get positive slip producing positive force.

Can you please clarify the coordinate system that is used?

Maybe we can add this to the readme? I did not notice any descriptions about this in the package, thanks!
