Fix or clarify copyright information

I was looking on a google search and stumbled across your code. I like your implementation however as of right now, no one has legal rights to use it.

Specifically, the heading comments in your files denote that you are the sole owner and proprietor of the code.

Would you mind declaring in either the readme or the files that the project is MIT License?

Nit picky thing I know but its important to the open source community as a whole.
