Find and add a license

[bolismauro]

We need to find a good license for Katana.
I'd stick with the famous ones. MIT, for instance, seems very common

Additional note, should we put the license also in the header? What I mean is something like this
https://github.com/Alamofire/Alamofire/blob/master/Example/Source/DetailViewController.swift#L4

I would choose MIT too (no GPL or people we'll hate us :D)
For the license notice, you might add it in the header as in the example you posted, but I would go for a shorter version just reporting something like:

Copyright 2016 ....
Distributed under the MIT License.
See the LICENSE file for more information.

The complete license statement should be in a LICENSE file in the root folder.

Just to give some context, almost any big iOS framework is under MIT.
Almost 90% of big iOS frameworks (source: github swift trending projects last month ordered by most starred) is not including license in the header, just copyright.
