Parametric Compound Planetary Transmission

Yet another planetary model generator. There are a lot of planetary models out there, but few seem to be designed to be modules easily integrated into a larger system. Hopefully this is generic enough to be used for that purpose. A helpful online compound planetary gear calculator is at: https://planetarygenerator.mateuszdrwal.com/ Since makerlab doesn't allow shared user libraries, I had to combine a bunch of the source files into one giant scad file.
