Add license file

[jstncno]

Hi,

I am wondering if you'll allow the inclusion of an open source license for this project. There are some fascinating logic in this project that I would like to use in my own projects (particularly in my personal website), but would require some minor changes in order to work in my own environment.

It is my understanding that I am not allowed to do this due to copyright infringement, since you do not explicitly specify a license which your code is under. Will you consider including an open source license?

Thanks!

oops, I think I spoke too soon. I found the license specified in your bower.json file:
https://github.com/donnieberg/accessible-color-palette/blob/master/bower.json#L17

I've added the MIT license in pull request #10 to state its use explicitly
