5. Factor out the unit-norm basis (and operator symmetry) tests once
all of the algebras pass.
-
-6. Refactor the current ungodly fast charpoly hack (relies on the
- theory to ensure that the charpolys are equal.)
-
-7. Implement random_instance() for the main EJA class.
-
-8. Implement random_instance() for the subalgebra class.
