    Description:
        Given a list of values X and a list of values Y, determine
        whether each value in X is greater than or equal to each
        corresponding value in Y. Equal pairs will return `True`.

        >>> greater_than_equal_to = GreaterThanEqualTo()
        >>> greater_than_equal_to([2, 1, 2], [1, 2, 2]).tolist()
        [True, False, True]
