-0. Add tests for orthogonality in the Peirce decomposition.
+1. Add references and start citing them.
-1. Add CartesianProductEJA.
+2. Profile (and fix?) any remaining slow operations.
-2. Check the axioms in the constructor when check != False?
+3. Every once in a long while, the test
-3. Add references and start citing them.
