 This gist is an offshoot of the one by Michael Cox at https://gist.github.com/michaelcox/3800736. 
 I had been looking for a testing solution for a long time, and his code didn't quite work for me, 
 so I thought I'd share what finally did.

 In all the files I'm showing here, there are additional lines of code that are omitted for brevity.
 If you'd like to see the whole thing in action, you can find it at 
 `https://github.com/danascheider/canto`.

 Relevant parts of my directory structure looked like this. The ./js/lib/chai and 
 ./js/lib/mocha directories are the same directories that show up in your node_modules 
 folder when you run `npm install`, but for the sake of clarity, I'm only showing the files 
 I reference in this gist.
