  4.  * RAINFALL STATISTICS
  5.  * ____________________________________________________________
  6.  * This program tracks the total rainfall for each of 12 months
  7.  * and displays total, average, highest, and lowest months.
  8.  *
  9.  * Computation is based on the formula:
  10.  * TotalRainfall += rainfall[]
  11.  * AverageRainfall = TotalRainfall / Num_months
  12.  * ___________________________________________________________
  13.  * INPUT
  14.  *		rainfall:	Monthly rainfall figures inputted by user
  15.  *		
  16.  * OUTPUT
  17.  *		TotalRainfall: Total rainfall for the year
  18.  *		AverageRainfall: Average monthly rainfall
  19.  *		HighestMonth:  Month with highest rainfall
  20.  *		LowestMonth:   Month with lowest rainfall
