class ShapeSet from TopOpeBRepBuild
---Purpose:
-- Auxiliary class providing an exploration of a set
-- of shapes to build faces or solids.
-- To build faces : shapes are wires, elements are edges.
-- To build solids : shapes are shells, elements are faces.
-- The ShapeSet stores a list of shapes, a list of elements
-- to start reconstructions, and a map to search neighbours.
-- The map stores the connection between elements through
-- subshapes of type <SubShapeType> given in constructor.
-- <SubShapeType> is :
-- - TopAbs_VERTEX to connect edges
-- - TopAbs_EDGE to connect faces
--
-- Signature needed by the BlockBuilder :
-- InitStartElements(me : in out)
-- MoreStartElements(me) returns Boolean;
-- NextStartElement(me : in out);
-- StartElement(me) returns Shape; ---C++: return const &
-- InitNeighbours(me : in out; S : Shape);
-- MoreNeighbours(me) returns Boolean;
-- NextNeighbour(me : in out);
-- Neighbour(me) returns Shape; ---C++: return const &
