Flatten directory structure

[annayqho]

@davidwhogg does it make more sense to flatten the existing directory structure or to simply make a new repository and move the current version of the code there?

flatten existing -- as long as you use git mv to move things, the history will be preserved. If you create a new repository you lose history!

you can delete old versions -- they remain in the git history so long as you don't start a new repo.
