package SMDS 

	---Purpose: This package provides the classes Mesh and MeshElement
	--          
	--          class Mesh: 
	--          -  contains the main definition of the 
	--             mesh and have access to the MeshElement objects
	--             
	--          class MeshElement:  
	--           -  defines the  topological constituants of the Mesh (i.e
	--              the Node, Edge, Face and Volume entities.
	--              
	--          These two last classes  inherits from an abstract
	--          class MeshObject.

    --          TOP_VERTEX   : to characterize a node with a CAD vertex
    --          TOP_EDGE     : to characterize a node with a CAD edge
