Could you add a License?

Please could you add a license file to this repo. Ideally it would be the MIT license, or any other opensource license. As you are the copyright holder {only} you can pick any one, (or more) license(s) for your code.

Thank you.

I second this. You aren't open source without an open source license. We cannot use your library in our projects, now matter how much we wanted to.
