    The totalistic rule as described in NKS. The average color is mapped to a whole number in [0, k - 1].
    The rule number is in base 10, but interpreted in base k. For a 1-dimensional cellular automaton, there are
    3k - 2 possible average colors in the 3-cell neighbourhood. There are n(k - 1) + 1 possible average colors for a 
    k-color cellular automaton with an n-cell neighbourhood.
    :param neighbourhood: a k-color array of any size
    :param k: the number of colors in this cellular automaton, where only 2 <= k <= 36 is supported
    :param rule: the k-color cellular automaton rule number in base 10, interpreted in base k
    :return: the result, a number from 0 to k - 1, of applying the given rule on the given state
