Find square root using Newton's Method -- Ruby version (we use a trick to get a good starting seed value)

	# https://www.codewars.com/kata/square-root-without-using-library-math

	# the challenge stipulates: don't require any libs, don't use ** operator (exponentiation)
	# the challenge also says all inputs will already be perfect squares of integers
	# This code works for very large integers as well as small ones
