Comment 12 for bug 1848524

I'll start working on the Cataloging nav file. Here are the steps that we seem to need for each section (using Blake's commit "Navigation: Acq is done" as an example):

- Add chapter labels to nav file items
- To match existing docs "chapter" level headings, combine adoc files as needed so that each "chapter" from the old docs structure has a single file linked from the nav
- Upgrade all heading levels in each adoc file so that the top-most heading is a "Level 1" heading (example: "= Chapter Name =")
- Add ":toc:" below top heading of each file
