Takes a binary STL file as input and generates a SVG that contains the
triangles "folded flat" so that they can be laser cut.

Work in progress -- not yet feature complete.
`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.
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.
* Marking mountain or valley folds.
