Massive Wiki Builder redesign notes and plans

2022-09-18: Bill has drawn a dataflow style diagram with two aims in mind:
1. illustrate the top-level Massive Wiki builder data processing; and
2. calling out key datastructures that can be refactored into a multi-purpose data structure to support MW website properties:
- fuzzy linking of wiki pages
- wiki full-text search
- multiple views of all wiki pages: by name, by date, and link to most-recent changed subset.
