General
	cluster: implementation_interface
	description: 
		"Base class for Eiffel Vision implementation interface. 
		Eiffel Vision uses the bridge pattern. See notes in ev_any.e) 
		Descendents of this class are coupled to descendants of EV_ANY 
		(the base class for the Eiffel Vision interface) which provide user 
		access. When a class requires different implementation on different 
		platforms descendents of this class have further descendants with 
		an _IMP suffix. 
		eg. If button needs platform specific code then 
		    - EV_BUTTON is the user interface, (descendant of EV_ANY) 
		    - EV_BUTTON_I is the implementation interface, 
		      (descendant of EV_ANY_I) 
		    - EV_BUTTON_IMP is the native implementation. 
		      It is implemented once for each platform, the actual class 
		      included in a system at 
		      compile time is determined by the Ace file."
