Watching Files with FS-Notify!

This week we continue laying out the groundwork for our "Haskellings" project. A key part of the this program is the automated aspect of "watch" mode. A user should be able to modify their file and then immediately see the results of their changes in the watcher window. This week, we get familiar with the fsnotify package, which lets us watch files and directories and take actions in our program when they change!
