        Returns:
        the chained closure
        Throws:
        IllegalArgumentException - if the closures array is null

        Parameters:
        closures - a collection of closures to chain
        Returns:
        the chained closure
        Throws:

        closure1 - the first closure, not null
        closure2 - the second closure, not null
        Returns:
        the chained closure
        Throws:
        IllegalArgumentException - if either closure is null
