Default Nexus jackshaft speed calculator

Like a hundred rpm/gear calculators that came before, I wanted to see some specific adjustments related to MY setup. So I made another one.

It goes, crankshaft->internal speed reducer-> engine sprocket-> tranny-> rear sprocket /wheel .

Tranny has input and output sprockets too.

The default values are the ones installed on my scooter as it is today.
