The following statistics are computed from various track. The meanings and definitions of each statistic is as follows:
  * Track_Line: The connected line of locations along a single track
  * Travel: The total length of the track from the first point to the last point.
  * Cycle_Count: (Track_Line/Track intersections) / 2
  * Cycle_Time: Same as Moving_Time
  * Avg_Seconds_Per_Cycle: Cycle_Time / Cycle_count
  * Moving_Time: The time during which a vehicle moves during the entire day.
  * Average_Speed: Travel / Moving_Time
  * Average_Cycle_Length: Travel / Cycle_Count
  * Average_Move_Time: Moving_Time / Cycle_Count
  * Working_Time: Defined value of 
      - Morning_Start_Time
      - Morning_End_Time
      - Afternoon_Start_Time
      - Afternoon_End_Time
  * Cost_Hours: Total Working_Time for the day
  * Minutes_Per_Hour: Cycle_Time / Cost_Hours

Notes:
  * Lengths are computed by linear X-Y projected distances between adjacent track points. (track altitude is ignored)
  * If Working_Time is not defined, Morning_Start == Track_Start, Afternoon_End == Track_End, no lunch period.
  * The "Moving" (for Moving_Time) is defined as:
     * time between adjacent points < 3 seconds AND
     * velocity between points > 0.5 FP


Example loop to calculate moving time and moving distance:
<code>
   // Uses some trackwork conventions for methods, reader is encouraged to translate 
   // to the appropriate idiom for their environment.
   
   //
   // Points are assumed to be order in time such that time(pt[0]) < time(pt[1])
   //
   int movingTime = 0;
   float movingDistance = 0.0;
   
   for( int i = 1; i < GetNPoints(); i++ )
   {
      CAgVertex v1 = GetAgVertexAt(i);
      CAgVertex prev = GetAgVertexAt(i-1);

      time_t seconds = GetUTCTimeAtIndex(i).GetTimeT();
      time_t prevSeconds = GetUTCTimeAtIndex(i-1).GetTimeT();

      float distanceDelta = v1.Distance(prev);
      int prevTimeDelta  = CAgTime::GetTimeDifferenceSeconds(GetUTCTimeAtIndex(i), GetUTCTimeAtIndex(i-1));
      float tmpspeed = (prevDelta > 0) ? distance/prevDelta : 0;
			
      if( (prevDelta < idleTime) && (tmpspeed > idleFPS) )
      {
         movingTime += prevTimeDelta;
         movingDistance += distanceDelta;
      }
      
      printf( "Moving seconds: %d\n", movingTime );
      printf( "Moving feet   : %d\n", movingDistance );
   }
