"""Finance Atlas app package.

Puts the vendored `bit-ui` submodule on `sys.path` so `import bit_ui` works.

It happens here rather than in `app.py` because the tests import `src.*`
directly without going through `app`, and both entry points need it. One
insert, at the one place everything else passes through.

`space/vendor/bit-ui` is a git submodule. If it is empty, the checkout was made
without `--recursive`:

    git submodule update --init --recursive
