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.
This adds better comments, sane defaults for most parameters, and
improved caching of test data.

This is cleanup relating to a naming decision that we made awhile ago
but never got around to.
