closes and terminates all resources of a live GUIObject instance.
- To use , you first need to load GUIKit using Needs["GUIKit`"].
- programmatically ends an interface's session (which is normally ended interactively by user actions such as closing the window), both closing and disposing of all related resources.
- forces the termination of interface resources even if an initial GUIRun might have requested that the interface live on past its closing by using the option ReleaseMethod->Manual.
- Use CloseGUIObject instead of to ensure the original life cycle intent of a GUIRun call.
