OpenScad Surface Solids 1.1

The previous incarnations of the library have been good for laying down generic Bezier surfaces, but it was very picky when it came to actually turning them into .stl files that are printable.

This thing will more readily turn your surfaces into .stl files. It makes a modification to the Renderer.scad file. Specifically, the DisplayQuadShards() routine. It now takes an array which tells it which of the 'edge' faces to generate.

Thus, instead of generating all the triangles as polyhedra, it will actually generate a full 'shell'. The 'top' is complete, and the 'bottom' is complete, but only the outside edges of the entire surface are complete. So, there are no interior walls, which end up causing problems for the shape being 2-manifold.

What this means is there is essentially one giant solid to process rather than a whole bunch of little ones. This makes CGAL much happier, and pieces that would not be printable before are now printable, as evidenced by the included .stl fi
