This change renames directories in preparation for the great package
rename. The repository is now in a broken state because the code
itself hasn't been updated. However this should ensure that git
correctly preserves history for each file.
Also throwing in a proof-of-concept MR that I'd like to run in production, and then scrap once the meaty MR is finished (e.g. exploding Recurring billing events into OneTimes).

This frankenclass was starting to get a little cluttered, especially once I add the ChildEntityInput/Reader.
