 Contract: sum_contents : double[] int -> double
 Purpose: compute and return the sum of the <size>
          values in <numbers> array.

 Examples: if const double SIZE1 = 4; and 
              double arr1[SIZE1] = {1.5, 2, 0.3, 5.46};, then 
              sum_contents(arr1, SIZE1) == 9.26

           if const double SIZE2 = 0; and
              double arr2[SIZE2] = {}; then
           sum_contents(arr2, SIZE2) == 0
