Demonstrate gregorian chant notation

This file pretty nicely demonstrates what still does
not work among ligatures: (i) horizontal spacing between ligatures and
lyrics aligment is broken; (ii) lily crashes when removing
Stem_engraver, but still using Slur_engraver (this is useful needed
for the \addlyrics feature when no slurs are to be typeset); (iii)
episem causes a parse error (this used to work a while ago); (iv)
support for augmentum dots is missing; (v) accidentals must be placed
before the ligature (not demonstrated in this example)."
