@dustinstansbury Hey Dustin, thanks for allowing us to add your Rethinking notebooks to our examples gallery! Please have a peek at this PR and see if this works for you. I've mainly edited the very start and very end of each notebook, to make headers, etc. consistent with the rest of the site. That basically involved pulling code out of your initialization script and placing them directly in the notebooks, and adding attribution to you and McElreath. I've included your original license file in the subdirectory.

I pushed a commit that sorts notebooks by the raw name before rendering the gallery. This puts the rethinking notebooks in order, but it also reshuffles all the other categories. I don't personally mind for two reasons:

1. It appears the over we previous got was semi-random
2. If we don't like the new ordering, we can rename notebooks with number prefixes like 01_introduction, 02_dimensionality, 03_linear_regression. This also makes it obvious what the ordering is supposed to be.

Happy to be over-ruled on this though.

What do you think of putting the lecture numbers in the titles of the notebooks that are displayed in the gallery? That would make it more obvious the order that one is supposed to view them in.

Yeah, I can change the titles (and the file names).
