package Geom2dAPI

	---Purpose: The  Geom2dAPI  package  provides  an  Application
	--          Programming Interface for the Geometry.
	--          
	--          The API is a set of classes aiming to provide :
	--          
	--          * High level and simple calls  for the most common
	--          operations. 
	--          
	--          *    Keeping   an   access  on    the    low-level
	--          implementation of high-level calls.
	--          
	-- 	    
	-- 	    The API  provides classes to  call the algorithmes
	-- 	    of the Geometry
	-- 	    
	-- 	    * The  constructors  of the classes  provides  the
	-- 	    different constructions methods.
	-- 	    
	-- 	    * The  class keeps as fields the   different tools
	-- 	    used by the algorithmes
	-- 	    
	-- 	    *   The class  provides  a  casting  method to get
	-- 	    automatically the  result  with  a   function-like
	-- 	    call. 
	-- 	    
	-- 	    For example to evaluate the distance <D> between a
	-- 	    point <P> and a curve <C>, one can writes :
	-- 	    
	-- 	        D = Geom2dAPI_ProjectPointOnCurve(P,C);
	-- 	    
	-- 	    or
	-- 	    
	-- 	        Geom2dAPI_ProjectPointOnCurve PonC(P,C);
	-- 	        D = PonC.LowerDistance();
	--
