Title: Reccommended License for organizations that legally need one defined

This is simply a recommendation. Most organizations cant use this gem without the LICENSE clearly defined. =]

Other license types are MIT, Apache etc. You could choose another one, however, the Ruby license should ensure that anyone using this won't have a problem.
