Export toxiclibs mesh from ruby-processing to PovRAY

Here is my test ruby processing sketch (using my customised toxiclibscore.jar), that exports the toxiclibs mesh as a PovRAY mesh2 object, written to a PovRAY inc file.

Here is the pov file, that uses the geometry from the exported ruby-processing sketch, to create a PovRAY scene description file.
