class ShellSplitter from BOP 

	---Purpose:  
    	---  the algorithm to split (multiconnexed)   
    	---  shells on a solid onto biconnexed shells 
	---  when each edge is shared by only two or one  
    	--   faces       

uses 

    Shell  from TopoDS,
    ListOfShape from  TopTools, 
    
    ListOfListOfShape from BOPTColStd, 
    
    EdgeInfo                         from BOP,
    IndexedDataMapOfEdgeListFaceInfo from BOP
