I don't think it's unreasonable to expect that inputs to mapalgebras
be on the same alignment. I do thing that utilities for re-sampling
whole tables need to exist to that it's possible to run full analyses
inside the database, but I think requiring alignment for mapalgebra
will solve more problems (in terms of people getting the results they
"expect") than trying to plaster over it with automagical code.
