package AIS2D

	---Purpose: FOR APPLICATION INTERACTIVE SERVICES
	--          
	--          This package provides the classes and methods
	--          to the maintenance of the high level 2D visualization . 
	--          The central entity is Interactive Context for easily 
	--          piloting presentation and selection.
	--          AIS2D package proposes the classes of standard Interactive Objects  
	--          and this one allows to implement users classes of interactive objects,
	--          by respecting a certain rules of creating of Interactive Object.
