Dependencies and Package Databases

Here's the final video in our Haskellings series! We'll figure out how to add dependencies to our exercises. This is a bit trickier than it looks, since we're running GHC outside of the Stack context. But with a little intuition, we can find where Stack is storing its package database and use that when running the exercise!

Next week, we'll do a quick summary of our work on this program, and see what the future holds for it!
