Problem: processData

Write a static method processData
   that takes as a parameter a Scanner holding a sequence of integers and that
   reports each of the cumulative sums of the sequence along with the average
   of the numbers.  For example, if the Scanner contains the following data:

        8 4 2 9 7 13 5 9

   your method should produce the following output:

        Sum of 1 = 8
        Sum of 2 = 12
        Sum of 3 = 14
        Sum of 4 = 23
        Sum of 5 = 30
        Sum of 6 = 43
        Sum of 7 = 48
        Sum of 8 = 57
        Average = 7.125

   Notice that the various lines of output report the sum including just the
   first number, then including the first two numbers, then including the first
   three numbers, and so on, up to the sum including all numbers.  The final
   line of output reports the average of the sequence of numbers.  Notice that
   this is the average of the numbers themselves, not the average of the
   cumulative sums.

   The amount of output will vary depending upon how many numbers are in the
   sequence.  For example, if the Scanner contains the following values:

        1 2 3 4

   the method should produce the following output:

        Sum of 1 = 1
        Sum of 2 = 3
        Sum of 3 = 6
        Sum of 4 = 10
        Average = 2.5

   You are to exactly reproduce the format of these sample outputs.  You may
   assume that the Scanner has at least one integer to be processed.
