Import OpenSCAD code

Introduction
OpenSCAD is a 3D CAD programm using the same geometric core as FreeCAD (OCCT).

But while FreeCAD uses a visual approach OpenSCAD uses a programming interface to perform 3D operations.

The OpenSCAD workbench can be used to import OpenSCAD object code and to have access to some of the

mesh operations possible with OpenSCAD.
