Add a LICENSE file?

[npch]

It's not clear what the license is for this code just by looking at the files in the repository - adding a LICENSE.md/LICENSE.txt file would clarify this (see: https://help.github.com/articles/open-source-licensing/)

PS Thanks for releasing the code, really useful for trying out on my own work.
PPS Try it out on source code as well...

Seconded! I'd love to help write documentation for this once the license gets set.

I suggest use this website to choose a license: http://choosealicense.com/licenses/
If you don't want to think about license then consider Public Domain.
