Sinoid Sphere Plotter - Parametric Curves in 3D

This is a early basic version to create a 3D Model using polar / spherical coordinates.
It is very simple. You can change the functions only in OpenSCAD.

I tried to improve the speed, but then OpenScad complained about problems with 2- manifolds. Anyone with ideas to make it faster is welcome!

- Added a "scaly fast" mode in version 2.
