/*
this engraver glues together stems, rests and note heads into a NoteColumn
It also generates spacing objects. Originally, we have tried to
have the spacing functionality at different levels.
-
+
- by simply using the sequence of Separation-item as
spacing-sequences (at staff level). Unfortunately, this fucks up if
there are different kinds of tuplets in different voices (8th and
spacing engraver don't know where to connect the last note of the
voice on the right with), but we don't complain about those, and let
the default spacing do its work.
