+---Purpose: 
+-- Classify faces and shells.
+-- shapes are Shells, Elements are Faces.

+    ---Purpose: Creates a classifier in 3D space, to compare : 
+    -- a face with a set of faces
+    -- a shell with a set of faces
+    -- a shell with a shell

+    ---Purpose: classify face <F> with shell <S>
+    returns State from TopAbs;

+    ResetShape(me : in out; S : Shape);
+    ---Purpose: prepare classification involving shell <S>
+    -- calls ResetElement on first face of <S>
+    
+    ResetElement(me : in out; F : Shape);
+    ---Purpose: prepare classification involving face <F>
+    -- define 3D point (later used in Compare()) on first vertex of face <F>.
+    
+    CompareElement(me : in out; F : Shape);
+    ---Purpose: Add the face <F> in the set of faces used in 3D point
+    -- classification.
+    
+    State(me : in out) returns State from TopAbs;
+    ---Purpose: Returns state of classification of 3D point, defined by 
+    -- ResetElement, with the current set of faces, defined by Compare.
