License Confusion

[GlenKPeterson]

Thank you for your project. I found it on StackOverflow here: https://stackoverflow.com/a/14999203/1128668

I can see an MIT licence file in the project, but at the top of the single .js file, it says "License: GPL" in the comment on line 15. Which is it? I can't use GPL code at work, so I'd prefer MIT (or Apache, Eclipse, or even LGPL). I've created a pull request #6 changing that to "MIT" (plus some other changes) if that's what you want.
