ccaabbss() computes the absolute value,  or modulus, of its complex argument _z.
The absolute value of a complex number is the length of the hypotenuse of a
right triangle whose  sides are given by the real  part _r and the imaginary
part _i.  The result is  the square root  of the sum  of the squares  of the
parts.
