pub fn best_choice(
options: &[Vec<Pitch>],
rules: EnharmonicRules,
) -> Result<Vec<usize>>Expand description
Which option of each position scores best under rules, one index per
position: the heart of music21’s bestPitches. Combinations are tried
in the order itertools.product lists them, and the first strictly
lowest wins. A position with no options leaves nothing to choose.
