License unclear

[goodwink]

There doesn't seem to be a LICENSE file or anything in the README.md about what the license for this code is, other than that it has been released as "open source" which could mean anything. Could you please add an explicit license so that the community will know what it may or may not do or add something to the README.md releasing it as public domain explicitly if you don't wish to license it?

Thank you very much for making this code available!
