Some quick pointers:

- grob-cause is inserted in lily/stencil-interpret.cc

- you need to add another expression type, mark-object (perhaps,
grob-cause could even be expressed as mark-object), and define
corresponding routines in output-*.scm

- you will need to make some symbol emit a new type of expression. As
a first approach, you could modify the stencil coming out of
Bar_line::print

- If you get that working (ie. get the marks to appear in the .ps),
try modifying Bar_number_engraver to add a bar-number property to the
object, which you use for defining the mark name.

good luck
