Licensing of submodules

[urbanslug]

1. Advice on a license in the README
2. Not impose a license on a submodule
3. Is there a way to have a fallback license if a submodule lacks one?
4. Which license would we advise/fall back on?

I suggest we use an MIT license. Let someone do whatever they want with the presentations.

People submitting presentations should definitely be encouraged to choose a license themselves and make it clearly stated in the presentation itself (ie on the footer of the last slide). Also, I think the Creative Commons licenses are more appropriate than GPL/MIT/etc for works like presentations and academic publications.

This makes a lot of sense.
