No license explicitly stated

[esammer]

We'd like to use this project but noticed no license was explicitly stated. I was hoping to convince you to declare a license. If you don't have a preference, ASF, BSD 2 or 3 clause, or MIT are preferable. ;)

Thanks!

@esammer if still desired and the license in build.sbt is not sufficient I can add a license.md. Apache 2 is whats in the build.sbt
