Indices

[MRoth1910]

Code is borrowed from the Nocturnale Romanum in order to build indices necessary to make this a useful book.

However, a system to actually put material in the index is needed, particularly to track variations (usually with or without Alleluia). Cataloging the contents of the vesperale (plus 1960, proper of France, and supplements) should have been done first, but better late than never. This list needs to be compared to the final index.
