STL to FACET model geometry file converter

This script imports an STL file and writes a .facet file commonly used by Xpatch, etc.

This file uses import_stl_fast to pull in model geometry and write an appropriate .facet file. If you require the ability to import binary stl files, import_stl_fast can be replaced with another importer from the file exchange.

The current version does not have inputs for different materials.
