Title: my latest work

This pull request includes the (nondependent) recursion principle for the circle,
with the circle defined as BZ, without the aid of Higher Inductive Types.

It remains to prove the (dependent) induction principle, which I expect will
follow the same general line of argument. And that has been shown to establish
the uniqueness of BZ.
