Create a function that takes one, two or more numbers as arguments and
adds them together to get a new number. The function then repeatedly
multiplies the digits of the new number by each other, yielding a new
number, until the product is only 1 digit long. Return the final product.
Examples
-6
sumDigProd (16, 28)
// 16 + 28 = 44
// 4 * 4 = 16
// 1 * 6 = 6
sumDigProd(0)
sumDigProd (1, 2, 3, 4, 5, 6) → 2
