ok should list all valid tests, perhaps when edit distance is too large

[brianhou]

I think we should be more clear what problems ok is able to test. Using Homework 1 as an example, it is not clear that there are no tests for if_function.

Interestingly, running python3 ok -q if_function actually runs the tests for hailstone. I do think that running python3 ok -q hailston and running hailstone is nice, so maybe we should introduce some maximum edit distance we are willing to run a test for. Typing the entire function name out (as opposed to q1) is a bit inconvenient though, so I think somehow mapping q1 to a list of functions to run doctests for would be preferable.
