OpenSource Prettification

* Added a LICENSE.md
* Updated README.md to be less awful; should only be sorta-bad now.
* Updated INSTALL.md to contain real installation instructions.
* Removed a likely outdated and misleadingly named test/ directory.
* Stubbed in a docs/ folder; doesn't contain docs yet.
