Added a License (BSD)

I suggest BSD (specifically the Revised BSD license, AKA BSD 3 Clause:
http://opensource.org/licenses/BSD-3-Clause
While it allows free usage by anyone, it prevents derivative works from claiming endorsement from RDI without express consent, while also remaining simple.

For example, they can't copy it, do malicious things with it, and drag RDI's name through the mud for it; though they can use it in commercial projects if they wish. See:
