Design an enumerator (e.g. named FBSuperEnumerator) that has two API's: - (id) nextObject; - (NSArray *) allObjects; // all objects remaining which, when given an input array that has content that can be either NSNumbers or NSArray, will expand all arrays embedded inside it. That is, given an input of something like @[@1, @[@2, @[@3, @4]], @[ ], @5], each call to nextObject will display items in the expected order.
