Mesh Generation
================

Objective
----------

Conversion of Geant4 geometries (CSG constructive solid geomery) into a BREP (boundary representation)
mesh of triangles in STL format.

Issues
~~~~~~~~

* maintaining identity of bits of the geometry in the mesh representation
* material properties
* surface properties
