    If you have a chain of objects where a.foo -> b, b.foo-> c, etc,
    use this to iterate over all objects in the chain. Iteration is
    terminated by getattr(x, attr) is None.

    Args:
        obj: the starting object
        attr: the name of the chaining attribute

    Yields:
        Each successive object in the chain.
