docs: Read the next interval histogram from the log, if interval falls within an absolute time range
  <p>
  Returns a histogram object if an interval line was found with an
  associated absolute start timestamp value that falls between
  absoluteStartTimeSec and absoluteEndTimeSec, or null if no such
  interval line is found.
  <p>
  Timestamps are assumed to appear in order in the log file, and as such
  this method will return a null upon encountering a timestamp larger than
  rangeEndTimeSec.
  <p>
  The histogram returned will have it's timestamp set to the absolute
  timestamp calculated from adding the interval's indicated timestamp
  value to the latest [optional] start time found in the log.
  <p>
  Absolute timestamps are calculated by adding the timestamp found
  with the recorded interval to the [latest, optional] start time
  found in the log. The start time is indicated in the log with
  a "#[StartTime: " followed by the start time in seconds.
  <p>
  Upon encountering any unexpected format errors in reading the next
  interval from the file, this method will return a null.
  @param absoluteStartTimeSec The (absolute time) start of the expected
  time range, in seconds.
  @param absoluteEndTimeSec The (absolute time) end of the expected
  time range, in seconds.
  @return A histogram, or a null if no appropriate interval found
