getNestMembers does not return any dynamically added members regardless 
of the host is a hidden class or non-hidden.    It returns an array of 
at least one element, the zeroth element is the nest host which can be a 
hidden class.  So for a hidden only nest, I see getNestMembers behaves 
consistently with an ordinary class with no NH attribute (i.e. no static 
members) and returns 1-element array consisting only the nest host.
