Write Gregorian Chant

I wrote this program for composing simple Gregorian Chants. It currently has support for Punctums, Virgas (left and right), Custos, Clef and you can build up the other common notes as well (Podatus, Clivis, Scandicus, Salicus, Climacus, Torculus, Porrectus, etc)
The user interface is very straight forward (just click where you want the note.) Currently only one line can be composed at a time and you must copy and paste the notation into another program if you want to save or print.
