Added some smoothing for spheres and cylinders
unfold reads a binary STL file on standard input and generates a
SVG that contains the triangles "folded flat" so that they can be
laser cut. It will output multiple groups in the SVG file that
will need to be re-arranged to fit on the laser cutter bed.

This is a work in progress -- it is not yet feature complete. Current features:
Collision detection works to build a non-overlapping set of triangles.
Coplanar triangles will be merged if possible.
Mountain/valley folds are marked. Dashed line means valley fold.
Starting face can be selected or randomly chosen; some produce better results than others.
stl-convertscript can convert OpenSCAD ASCII STL files into binary STL files for
Among the features that it could use:
A better heuristic for finding the maximum non-overlaping set of triangles (Currently breadth-first search is used, with a slight preference for coplanar triangles)
Tabs for securing parts together.
Collapsing of very small or very thin triangles.
wireframe reads a binary STL file on standard input and generates an
OpenSCAD file that has each vertex replaced with a 3D printable
connector to create a large-scale version of the object.

This is very beta! It desperately needs some command line options and some smarts in labeling the connectors, especially if the structure is not regular. Also, it does not detect intersections between beams or if the nodes are too close together.
