Rotation & angle of universal joint?

[Philippe Hurbain]

Notes:
It only works with uni ends with an origin at the center piece (like 62520.dat)

Not a huge restriction, to use universal joint ends with stupid origin (3712 and 575) you only have to translate them by 30 ldu to place their origin at the right place, apply script, and re-translate them in opposite direction (using relative grid).

I did very little testing.

I indeed think there is something not addressed, configurations where one i/o axle needs to be rotated. If I am not utterly wrong, this occurs when input and output axle do not sit in parallel planes. See attached example.
