  5.  * COMPUTE SHIPPING CHARGES
  6.  * _____________________________________________________________________________
  7.  * This program accepts and as input the weight of the user's package and the 
  8.  * distance the package is being shipped, validates it, then calculates and 
  9.  * displays the shipping charges. 
  10.  * 
  11.  * Computation will be based on the following input restrictions:
  12.  * - The package cannot weight less than 0 kg or more than 20 kg
  13.  * - The package cannot be shipped a distance less than 10 mi or more than 3,000
  14.  *   mi
  15.  * _____________________________________________________________________________
  16.  * INPUT
  17.  *   packageW    : Weight of the package
  18.  *   shipDist    : Shipping distance 
  19.  *   distMult    : Times greater than 500
  20.  *   rate_1      : Rate for packages that weight 0-2 kg
  21.  *   rate_2      : Rate for packages that weight 2-6 kg
  22.  *   rate_3      : Rate for packages that weight 6-10 kg
  23.  *   rate_4      : Rate for packages that weight 10-20 kg
  24.  *   rate_1Max   : Max weight for rate_1
  25.  *   rate_2Max   : Max weight for rate_2
  26.  *   rate_3Max   : Max weight for rate_3
  27.  *   rate_4Max   : Max weight for rate_4
  28.  *   lowerW      : Min package weight
  29.  *   upperW      : Max package weight
  30.  *   distRate    : Miles rates are based on, (rate per 500 mi)
  31.  *   lowerD      : Min shipping distance
  32.  *   upperD      : Max shipping distance
  33.  * 
  34.  * OUTPUT
  35.  *   shipCharge  : Cost of shipping
