Missing License spec

[anthonywu]

Hi there - this is a great library and definitely is a welcome addition to the Python community. To make this project's open source expectations known to others, you should add a LICENSE file. May I suggest the MIT license?

[anthonywu]

Ah I see you declared it as a BSD license type in setup.py. Sorry I overlooked that. I still suggest an explicit LICENSE file though.

Would you advice for MIT instead of BSD? I am open to the change if you think it would be beneficial

[anthonywu]

There are variants to the BSD license, you should be explicit regarding which of of the 3 you'd like to use: http://choosealicense.com/licenses/

Alternatively, you can choose the very common MIT license, which I think is functionally equivalent to your copyright intent.
