Apply public domain license to repo materials

Essentially waives all copyright claim to the materials we generated, i.e. making it Public Domain. Seemed like it would be appropriate. Of course if anyone would like to have a different license that's fine too, though I don't think we should go any more restrictive than CC BY 4.0 http://creativecommons.org/licenses/by/4.0/
