I added a primitive "folding" capability to the code.  Right now it really only
works for one fold at a time in a given region.  I need to play around with it
so you can fold already folded regions.

As you can see, the smaller the bending radius, the more points you need in the
mesh2 grid to avoid jagged edges along the fold.  I need to explore a more
efficient representation of the mesh and some code for sub-dividing the faces in
just those regions to avoid having a million faces in a single sheet of paper.
