This is why I put that in there. It really should not be named DG, but
there are reasons I thought it made sense.

I had not thought about a dual space, since I was not going to project into
it. I think you can just use whatever is the default.

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which their
experiments lead.
