8. def estimateJobTime(times: Seq[Double]): Option[Double]

   

   Given a list of "typical" times observed in a series of jobs of the same FlowStep, aggregates these times into a single estimate of the time that a "typical" reducer took in a "typical" job.

   Given a list of "typical" times observed in a series of jobs of the same FlowStep, aggregates these times into a single estimate of the time that a "typical" reducer took in a "typical" job. Suggested implementation: mean or median.
