+8. Factor out a class for matrices with real embeddings (i.e. not the
+   octonions).
+
+9. In fact, could my octonion matrix algebra be generalized for any
+   algebra of matrices over the reals whose entries are not real? Then
+   we wouldn't need real embeddings at all. They might even be fricking
+   vector spaces if I did that...
+
+10. Add HurwitzMatrixAlgebra subclass between MatrixAlgebra and
+    OctonionMatrixAlgebra.
