 Contract: sum_array : double[] int -> double
 Purpose: expects any array of numbers and how many numbers
//          are in it, and returns the sum of those numbers

 Examples: 
   consider this array:

   const int NUM_WTS = 5;
   double fish_wts[NUM_WTS] = {10, 20.5, 3, 4, 100};

   sum_array(fish_wts, NUM_WTS) == 137.5

        sum_so_far = sum_so_far + values[index];
