class EdgesBlock from HLRAlgo inherits TShared from MMgt

	---Purpose: An EdgesBlock is a set of Edges. It is used by the
	--          DataStructure to structure the Edges.
	--          
	--          An EdgesBlock contains :
	--          
	--          * An Array  of index of Edges.
	--          
	--          * An Array of flagsf ( Orientation
	--                                OutLine
	--                                Internal
	--                                Double
	--                                IsoLine)
