1 1. Add CartesianProductEJA.
3 2. Check the axioms in the constructor when check != False?
5 3. Add references and start citing them.
7 4. Implement the octonion simple EJA.
9 5. Factor out the unit-norm basis (and operator symmetry) tests once
10 all of the algebras pass.
12 6. Add a TrivialEJA class and use it in the tests for is_trivial().
13 The random_eja() function should also be able to return these.
