class Spliter from LocOpe

	---Purpose: 

uses Shape                     from TopoDS,
     Face                      from TopoDS,
     ProjectedWires            from LocOpe,
     ListOfShape               from TopTools,
     DataMapOfShapeListOfShape from TopTools



raises NotDone      from StdFail,
       NullObject   from Standard,
       NoSuchObject from Standard

	---Purpose: Creates the algorithm on the shape <S>.

	---Purpose: Returns the faces of the "left" part on the shape.

    	---Purpose: Returns the list of descendant shapes of <S>.
    	returns ListOfShape from TopTools
	---C++: return const&
	raises NotDone from StdFail,
	       NoSuchObject from Standard
	--- The  exception  NotDone   is  raised  when  IsDone returns
	--  <Standard_False>. The exception  NoSuchObject is raised if
	--  <S> is not a subshape of the original shape.
