MOD computes N mod M.  N and M can both be either an integer or a list of
integers.  Thus there are 4 possible types of input: number mod number, number
mod list, list mod number, or list mod list.  Example: If N = {5,47,36,11} and
M=7, the answer is {5, 5, 1, 4}.  If both N and M are lists, they must have the
same length.
