Why do you use the NoteColumn here as the cause for the SlurStub?  It
would make much more sense to use the respective slur.  Then you don't
need a separate "surrogate" field since you can just use 'cause instead,
and you can \tweak a SlurStub via its Slur event, and most importantly
you don't need a special "initialize from surrogate" utility function
but can rather use an "initialize from cause" function.
