  5.  * Compute Rainfall Measurements
  6.  * ____________________________________________________________________________
  7.  * This program will accept data from the user about the rainfall and 
  8.  * temperature (highest and lowest) each month then calculate the total 
  9.  * rainfall, average monthly rainfall, which temperature was the hgiehst/lowest
  10.  * and what month it was during, and lastly the yearly average temperature!
  11.  * ____________________________________________________________________________
  12.  * Input
  13.  *   totalRainfall            :Total amount of rainfall in the month
  14.  *   highTemp                 :Highest temperature in the month
  15.  *   lowTemp                  :Lowest temperature in the month
  16.  *   avgTemp                  :Average temperature between lowest and high in the month
  17.  * Output
  18.  *   totalRainfall            :Total amount of rainfall in the year
  19.  *   averageMonthlyRainfall   :Average amount of rainfall in the year
  20.  *   totalAverageTemp         :Average temperature in the year
  21.  *   highestMonth             :Highest temperature and the month it came from
  22.  *   lowestMonth              :Lowest temperature and the month it came from
