New in version 2.0.
Change leaf to augmented tuplet with proportions:
abjad> note = Note(0, (3, 16))
abjad> print leaftools.leaf_to_augmented_tuplet_with_proportions(note, [1])
{@ 1:1 c'8. @}
abjad> print leaftools.leaf_to_augmented_tuplet_with_proportions(note, [1, 2])
{@ 1:1 c'16, c'8 @}
abjad> print leaftools.leaf_to_augmented_tuplet_with_proportions(note, [1, 2, 2])
{@ 5:8 c'64., c'32., c'32. @}
abjad> print leaftools.leaf_to_augmented_tuplet_with_proportions(note, [1, 2, 2, 3])
{@ 2:3 c'64, c'32, c'32, c'32. @}
abjad> print leaftools.leaf_to_augmented_tuplet_with_proportions(note, [1, 2, 2, 3, 3])
{@ 11:12 c'64, c'32, c'32, c'32., c'32. @}
abjad> print leaftools.leaf_to_augmented_tuplet_with_proportions(note, [1, 2, 2, 3, 3, 4])
{@ 5:8 c'128, c'64, c'64, c'64., c'64., c'32 @}
