Editing Tablature layout for viol music

The snippet defines a specialized group of rhythmic and tablature staves able to handle old english viol tablature scores.

The string tunings defaults to the most common viol in d but other usual tunings are also available.

The rhythm part is used to provide only the pace changes, and therefore must be provided as a supplementary voice.
