Comment (by tscrim):
The `cardinality` should work, but it is not there and is something we
should implement in generality. A default `is_unitary` that returns `True`
could perhaps go in `UnitalAlgebras`, but the cohomology ring is unital as
the sum of the 0-th degree components, correct (you had this in your
`__pow__` method too)? There should be a generic `is_commutative` test for
finite dimensional algebras with basis. I will open up a separate ticket
when I get to my office.
