Create an assessment directory

I've been doing a few take-home assessment recently, all of which I've attempted
to solve using Haskell. I'm having a good time, and I'm noticing strong and weak
points with my Haskell programming. I always attempt to apply any feedback a
reviewer gives me, and I'm storing my first drafts, second attempts, and
feedback here for now.

This recently attempt was for a role at Jane Street.
