-6. The main EJA element constructor is happy to convert between
- e.g. HadamardEJA(3) and JordanSpinEJA(3).
+6. We should compute whether or not the algebra is associative if it
+ is unknown. I guess the "associative" argument should be ternary
+ (True, False, None)? We should also figure out the correct
+ True/False values for the example classes, and of course add an
+ _is_associative() method.

+7. Set check_axioms=False for element-subalgebras outside of once or
+ twice in the test suite.
