Advances the iterator and retrieves the next member in the object.
If the end of the object is reached, FALSE is returned and member_name and
member_node are set to invalid values. After that point, the iter is invalid.
The order in which members are returned by the iterator is the same order in
which the members were added to the json.object.ObjectJson. The iterator is invalidated
if its json.object.ObjectJson is modified during iteration.

You must use this function with an iterator initialized with json.object_iter.ObjectIter.initOrdered; using this function with an iterator initialized with json.object_iter.ObjectIter.init_ yields undefined behavior.
