    What comes in:
      -- A sequence of numbers.
    What goes out:
      Returns the sum of the absolute values of the numbers.
    Side effects:   None.
    Examples:
      sum_all([5, -1, 10, 4, -33])
         would return 5 + 1 + 10 + 4 + 33, which is 53

      sum_all([10, -30, -20])  would return 10 + 30 + 20, which is 60
