Consider moving to a public domain licence

[lgalfaso]

This repository contains samples that people copy & paste for their projects. Having the current license adds an unnecesary burden to make sure that whatever they copy, have the correct license in place.

Consider changing the license to one that people can copy & paste samples without having to worrying about making sure that the corresponding license is preserved.

@lgalfaso I think that's a very good point! Which license would you propose?

[lgalfaso]

If possible, http://unlicense.org/ would make things the easiest.

I also think it's a good idea.

We'll just have to contact all contributors and get their approval, won't we?

[sbrannen]

Yes, I think that is all that is required.
