New in version 1.1.
Remove subsequence of weight at index:
abjad> from abjad.tools import sequencetools
abjad> sequencetools.remove_subsequence_of_weight_at_index((1, 1, 2, 3, 5, 5, 1, 2, 5, 5, 6), 13, 4)
(1, 1, 2, 3, 5, 5, 6)
Return newly constructed sequence object.
Changed in version 2.0: renamed listtools.remove_weighted_subrun_at() to sequencetools.remove_subsequence_of_weight_at_index().
