Missing Copyright?

[leopoldodonnell]

Hi, we're using inspec and are looking to expand our use by testing more of our infrastructure. You've got a great start here, but I can't use what you've got without a copyright. I will submit a pull request with an MIT copyright and hope you merge it - otherwise it would be great to know if you'd like to keep it as is, so others can move on.

If you're really busy, I'd be happy to take on the project.

A license would also make it easier for me to contribute. May I suggest Apache 2.0, the same as InSpec itself?
