[x] Add WriteManiplexesToFile and ManiplexesFromFile to the documentation.
[x] Add information on where the data comes from
[ ] Add a way to compute and then safely store auxiliary information on any maniplex file. (e.g., maybe you want to compute and store the lengths of all the 2-holes in an easy way)
[ ] Pull out some more reflexible maniplex families into separate generators
[x] Rework the general interface to small maniplexes to do more filtering while the data is being read and generated.
[ ] Split some of the data across multiple files to help performance. (e.g. stratify by size, separate orientable from non-orientable...)
(Removed "Add HartleyIDs" because that's already a separate issue)
