Iterable Business Objects

[samiebee43]

IMHO we should give self.bus_obj an iterable list of all business
objects, all of which should extend EnlightenBusinessObject or whatever,
with overridable methods update_visibility, post_init (to be fired after
all Business Objects are instantiated, etc.

Maybe we can make a iterable of business objects. We might consider automating it with python magic.. not sure if that's the best route.

No need to make an common ancestor class. Since Python is weakly typed such a class does not produce any benefits unless it provides additional functionality, such as default functions.
