TIQueue maintains a first-in first-out array, or queue, of interfaces. Use a TIQueue object to store and maintain a first-in first-out list.
To use the class properly as a queue, use the RSInterfaceCollections.TIQueue.Push(IInterface) and RSInterfaceCollections.TIQueue.Pop methods, not Add or Items.
