abjad.FeatherBeamContainer will subclass abjad.Container.
abjad.FeatherBeamContainer will steal much of the logic in rmakers.accelerando() and rmakers.feather_beam().
rmakers.accelerando() will be updated to return a list of feather-beam containers. (rmakers.accelerando() currently returns a list of tuplets.)
Users will be able to iterate feather-beam containers separately from tuplets, grace containers, and all other types of containers, which will make patterns like this straightforward:
for container in abjad.select.containers(voice):
if isinstance(container, abjad.FeatherBeamContainer):
leaves = abjad.select.leaves(container)
abjad.beam(leaves, beam_rests=True, stemlet_length=0.75)
