Sequencing Exercises in the Watcher

Our watcher program can keep tabs on our exercise files, but it doesn't have any notion of an exercise order. In this week's video, we'll fix this! Our watcher will focus on one specific "current" exercise. When we're done with that, it will move us on to the next one automatically! This video involves a good example of using recursion in our Haskell workflow. But even better, we'll see a rudimentary usage of an MVar to pass information between the threads of our program. Take a look!
