 // LapTimer is used to calculate average times per "Lap" in perf tests.
 // Current() reports the time since the last call to Start().
 // Store() adds the time since the last call to Start() to the accumulator, and
 // resets the start time to now. Stored() returns the accumulated time.
 // NextLap increments the lap counter, used in counting the per lap averages.
 // If you initialize the LapTimer with a non zero warmup_laps, it will ignore
 // the times for that many laps at the start.
 // If you set the time_limit then you can use HasTimeLimitExpired() to see if
 // the current accumulated time has crossed that threshold, with an optimization
 // that it only tests this every check_interval laps.
