I think John did most of the pyramid work, and IIRC it does work - the
five corner children are pyramids (and similar to the parent since we
only support 1st order pyramids) but I believe there's an inverted
sixth pyramid and some tets in the middle.  The really weird bit is
the rational (non-polynomial!) basis functions, but that won't be an
issue for fixing a topology-based method.

I don't know if pyramid adaptivity actually works, but I was able to
find an ancient Matlab script which draws the Pyramid children--they
are basically as Roy described.

I've attached the PDFs if you are interested Roy.  Not sure they will
make it to the list though... if anybody else wants them just let me
know.

It looks like the adaptivity for Pyramids never got implemented?
Pyramid5::embedding_matrix() just throws an error.

Which means I'll drop it for now.  If we can't refine pyramids yet
then that's just a missing feature that we can add at our leisure.
I'm fine with the library occasionally saying "we can't do that yet"
as long as it never says "we can do that: here's a wrong answer!"

Now to figure out the tets.. those we actually do refine.
