This class is intended to output free bounds of the shape
(free bounds are the wires consisting of edges referenced by the
only face).
This class works on two distinct types of shapes when analyzing
their free bounds:
1. compound of faces.
Analyzer of sewing algorithm (BRepAlgo_Sewing) is used for
for forecasting free bounds that would be obtained after
performing sewing
2. compound of shells.
Actual free bounds (edges shared by the only face in the shell)
are output in this case. ShapeAnalysis_Shell is used for that.

	ShapeAnalysis_FreeBounds (const TopoDS_Shape &shape, const Standard_Real toler, const Standard_Boolean splitclosed=Standard_False, const Standard_Boolean splitopen=Standard_True)
	Builds forecasting free bounds of the <shape>. <shape> should be a compound of faces. This constructor is to be used for forecasting free edges with help of sewing analyzer BRepAlgo_Sewing which is called with tolerance <toler>. Free edges are connected into wires only when their ends are at distance less than <toler>. If <splitclosed> is True extracts closed sub-wires out of built closed wires. If <splitopen> is True extracts closed sub-wires out of built open wires.
	ShapeAnalysis_FreeBounds (const TopoDS_Shape &shape, const Standard_Boolean splitclosed=Standard_False, const Standard_Boolean splitopen=Standard_True, const Standard_Boolean checkinternaledges=Standard_False)
	Builds actual free bounds of the <shape>. <shape> should be a compound of shells. This constructor is to be used for getting free edges (ones referenced by the only face) with help of analyzer ShapeAnalysis_Shell. Free edges are connected into wires only when they share the same vertex. If <splitclosed> is True extracts closed sub-wires out of built closed wires. If <splitopen> is True extracts closed sub-wires out of built open wires.
const TopoDS_Compound &	GetClosedWires () const
	Returns compound of closed wires out of free edges.
const TopoDS_Compound &	GetOpenWires () const
	Returns compound of open wires out of free edges.

static void	ConnectEdgesToWires (Handle< TopTools_HSequenceOfShape > &edges, const Standard_Real toler, const Standard_Boolean shared, Handle< TopTools_HSequenceOfShape > &wires)
	Builds sequnce of <wires> out of sequence of not sorted <edges>. Tries to build wires of maximum length. Building a wire is stopped when no edges can be connected to it at its head or at its tail.

	Builds sequnce of <owires> out of sequence of not sorted <iwires>. Tries to build wires of maximum length. Building a wire is stopped when no wires can be connected to it at its head or at its tail.
static void	SplitWires (const Handle< TopTools_HSequenceOfShape > &wires, const Standard_Real toler, const Standard_Boolean shared, Handle< TopTools_HSequenceOfShape > &closed, Handle< TopTools_HSequenceOfShape > &open)
	Extracts closed sub-wires out of <wires> and adds them to <closed>, open wires remained after extraction are put into <open>. If <shared> is True extraction is performed only when edges share the same vertex. If <shared> is False connection is performed only when ends of the edges are at distance less than <toler>.
static void	DispatchWires (const Handle< TopTools_HSequenceOfShape > &wires, TopoDS_Compound &closed, TopoDS_Compound &open)
	Dispatches sequence of <wires> into two compounds <closed> for closed wires and <open> for open wires. If a compound is not empty wires are added into it.
