Missing release v1.0

For openjournals/jose-reviews#21.

I think it makes sense to hold off on cutting a release until we resolve the other issues from review -- that way the tag position can reflect the paper most accurately.

Makes sense. Just wanted to throw up an issue since it's part of the review.

Notebooks 0 and 1 have version numbers in them as well. These should probably be automatically inserted using git describe, if they're even necessary at all.
