Stage 1 Repairing Rienzi and Prepping Prompt Book

[ebeshero]

• @dorothealint compares the photofacsimile of msR (original Mitford MS) to the Google Sheet tabulation, and correct comparisons with the prompt book there.

• If you want to, @dorothealint can check the 1828 print edition to compare as well. (Is it reflecting changes from the prompt book?)

• @ebeshero works on Schematron to capture and correct problems with <app> elements containing only a single rdg wit, to do some major cleanup on Rienzi.

• @ebeshero prepares Dorothea for adding <rdg> elements to existing (corrected) <app>s.
