//! 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 &
