Thanks, Nicolas.  This is a doc bug that was created when we got the 4 4
autobeaming right.  I will fix it soon.

This is a feasible beamSettings override, but it's probably not desirable.

The new autobeaming code requires that you set a *complete* set of beam
rules for any time signature.  This is not a complete set; it doesn't have
default behavior (but if no default behavior is in the beaming rule, it will
default to grouping at beatLength).

Thanks,

Carl
