This directory contains an attempt to simplify, cleanup, and extend
R.L.W.L.'s elastic object simulator. 

This attempt was temporarily suspended, in favor of a more modest
rewrite (see ../tese-rluis-v1/").

It now seems advisable to use a linked 3D subdivision data structure,
similar to the QuadEdge, as the basic modeling structure; with
conversion to vector/matrix form done only inside the simulator.
