Title: Skip a handful of doctests that

These tests tended to tended to fail pseudo-nondeterministically for me in some cases. In particular it would happen when running the tests through tox. Not sure why that was, but clearly these could in principle fail in other contexts too.

It's worth nothing that some of the failures seem to be due to the fact that coordinate frames' `__repr__` does not display the coordinate attributes in a deterministic order, so maybe that should be fixed separately..
