class ShapeSet from BOP
---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
--
uses

Orientation from TopAbs,
