   1 1. Add references and start citing them.
   2
   3 2. Profile (and fix?) any remaining slow operations.
   4
   5 3. When we take a Cartesian product involving a trivial algebra, we
   6    could easily cache the identity and charpoly coefficients using
   7    the nontrivial factor. On the other hand, it's nice that we can
   8    test out some alternate code paths...
   9
  10 4. Add dimension bounds on any tests over AA that compute element
  11    subalgebras.
  12
  13 5. The rational_algebra() stuff doesn't really belong in classes that
  14    don't derive from RationalBasisEJA or its as-yet-nonexistent
  15    element class.
