rand_look max (number_or_range)
Given a max number, produces a number between 0 and the supplied max value exclusively. If max is a range produces an int within the range. With no args returns a value between 0 and 1.
Does not consume a random value from the stream. Therefore, multiple sequential calls to rand_look will all return the same value.
