Pulley Library

This is a rewrite of the code by droftarts to see whether structuring a library like this using a cleaner separation of data and code and a functional approach (no global variables) would help in understanding and reusing the code. This work is offered in all humility as a product of my own attempts to learn openscad. I have only tried this on a few simple cases and not printed from it.

May 2014 - code updated slighly to OpenSCAD version 2014-03
