docs: Wrap to automatically capture information for the segment.
  @param {string} name - The name of the new subsegment.
  @param {function} fcn - The function context to wrap. Can take a single 'subsegment' argument.
  @param {Segment|Subsegment} [parent] - The parent for the new subsegment, for manual mode.
