Joe pointed out that TimeSignature was unsuitable as
the beam settings had nothing to do with the appearance
of the time signature.  Perhaps a better alternative
would be to define new properties of Beam (in beam-interface)
to hold the parameters which determine when the beam
should terminate.  The time-signature-dependent defaults
of beatLength, measureGrouping and beamGrouping could
be set up as defaults of the Beam grob whenever the time
signature changed, and would then be available to be
overridden/reverted as properties of Beam anytime before
any beam grob was created.  This would make it easy to
change the beaming within a constant time signature.
For varying time signatures changes could still
be made via \overrideTimeSignatureSettings.
