New Tool for Gregorian Propers

The propers tool that I began work on about a week ago has become useful enough that I thought it would be worthwhile to advertise its existence. It is a tool for producing PDFs of the propers for Sunday masses in the extraordinary form and will also allow you to apply psalm tones to the propers a la Rossini. I think it should be straightforward enough to use, but let me know if anyone has any further ideas or suggestions for it.

I have also included this propers tool in the latest version of the offline GABC Transcription Tools app for Chrome.
