Tuplet beams

Tuplet beams join notes in tuplets that can be joined with beams just like non-tuplet beams. You can make the same changes to tuplet beams that you can make to any other beam.

For example, duplet eighth notes do not need a bracket as they can be joined by a beam and notated using only a tuplet number/ratio.
