 - to_segments: transform to get back segment onsets, offsets, and labels from labeled timebins.
   Inverse of ``from_segments``.

+  - segment_inds_list_from_class_labels: helper function used to find segments in a vector of labeled timebins
   - remove_short_segments: remove any segment less than a minimum duration
   - take_majority_vote: take a "majority vote" within each segment bounded by the background label,
     and apply the most "popular" label within each segment to all timebins in that segment
