Can we remove the final folder from the starting code

Hi there,

I was going through the tutorial, which I think is great, but I think I'm spending a lot of time making sure I'm in the right file when starting to edit. We might want to remove the final folder and make it maybe a branch.

The final code is not that useful to compare with an in-progress version either since much changes when you add features in further steps on the tutorial.

Inspect the tutorial repository layout, especially the starting code and final folder, and compare how each supports following the tutorial. Determine whether the final code should be removed or moved to a branch, then verify that the tutorial remains easy to follow and that the final code is still available for comparison.
