I fought through the various tree view issues and got it to build a
directory list that's kind-of functional.
Please break and report issues on the repo.

On the first day, God created the heavens and the Earth
On the second day, God created the oceans.
On the third day, God put the animals on hold for a few hours,
   and did a little diving.
And God said, "This is good."
