package Primitives 

	---Purpose: This  package   describes   algorithms  to   build
	--          topological primitives.
	--          
	--          The algorithms  in  this package  are  generic. It
	--          contains :
	--          
	--           *   The Builder  signature   class. Describes the
	--           services    required  from    the  Topology  Data
	--           Structure to build the following primitives.
	--          
	--           * The  OneAxis generic class.  Algorithm  used to
	--           build rotational primitives.
	--               
	--           *  The  Wedge  generic  class. Algorithm to build
	--           boxes and wedges.
