class BoundaryEdges from SMDSControl inherits MeshBoundary from SMDSControl

	---Purpose: compute  the boudary edges  of a mesh that  is the
	--          edges that are shared  by only one face the result
	--          is a new  mesh created in the same  factory as the
	--          original mesh that contains only edges

uses

    Create(M: Mesh from SMDS) returns BoundaryEdges from SMDSControl;
    
    Compute(me: mutable) is redefined virtual;
