The tests will be checked in order, and the first one to fail will have
its docstring (in markdown) shown to the user.

The user submitted notebook has already been executed, and the contents of
the global namespace there is passed in as `ns` to each function.

You can use `@scored` decorator to specify that if a student gets all the
tests right, up to that test, they can be awarded that score.

You can test this locally by running:
