This package provides basic tools to explore the
topological data structures.

* Explorer : A tool to find all sub-shapes of a given
type. e.g. all faces of a solid.

* Package methods to map sub-shapes of a shape.

Level : Public
All methods of all classes will be public.

static void	MapShapes (const TopoDS_Shape &S, const TopAbs_ShapeEnum T, TopTools_IndexedMapOfShape &M)
	Stores in the map <M> all the sub-shapes of <S> of type <T>. Warning: The map is not cleared at first.
static void	MapShapes (const TopoDS_Shape &S, TopTools_IndexedMapOfShape &M)
	Stores in the map <M> all the sub-shapes of <S>.
static void	MapShapesAndAncestors (const TopoDS_Shape &S, const TopAbs_ShapeEnum TS, const TopAbs_ShapeEnum TA, TopTools_IndexedDataMapOfShapeListOfShape &M)
	Stores in the map <M> all the subshape of <S> of type <TS> for each one append to the list all the ancestors of type <TA>. For example map all the edges and bind the list of faces. Warning: The map is not cleared at first.
static TopoDS_Vertex	FirstVertex (const TopoDS_Edge &E, const Standard_Boolean CumOri=Standard_False)
	Returns the Vertex of orientation FORWARD in E. If there is none returns a Null Shape. CumOri = True : taking account the edge orientation
static TopoDS_Vertex	LastVertex (const TopoDS_Edge &E, const Standard_Boolean CumOri=Standard_False)
	Returns the Vertex of orientation REVERSED in E. If there is none returns a Null Shape. CumOri = True : taking account the edge orientation
static void	Vertices (const TopoDS_Edge &E, TopoDS_Vertex &Vfirst, TopoDS_Vertex &Vlast, const Standard_Boolean CumOri=Standard_False)
	Returns in Vfirst, Vlast the FORWARD and REVERSED vertices of the edge <E>. May be null shapes. CumOri = True : taking account the edge orientation
static void	Vertices (const TopoDS_Wire &W, TopoDS_Vertex &Vfirst, TopoDS_Vertex &Vlast)
	Returns in Vfirst, Vlast the first and last vertices of the open wire <W>. May be null shapes. if <W> is closed Vfirst and Vlast are a same vertex on <W>. if <W> is no manifold. VFirst and VLast are null shapes.
static Standard_Boolean	CommonVertex (const TopoDS_Edge &E1, const TopoDS_Edge &E2, TopoDS_Vertex &V)
	Finds the vertex <V> common to the two edges <E1,E2>, returns True if this vertex exists. Warning: <V> has sense only if the value <True> is returned
