code: public double getPercentile( double percentile )
      {
          Percentile p = new Percentile();
  
          return p.evaluate( m_times.m_values, 0, m_times.size(), percentile );
      }
docs: Get the nth percentile.  NB: This is also a fairly slow operation.
  
  @param percentile Percentile to get.
