This is potentially useful as an explanatory example. I am also
using this to create new figures to explain the process in talks/etc.

This is so that when we click over from the front page, we directly land
in the page that has all the thumb-nails with the tutorial titles.

Also, reordering the tutorials on the page in a somewhat more deliberate
fashion. We'll need to follow up and change the titles for all of these
tutorials.
