This structure holds an association between a vertex of a given profile of
the loft and one on the immediately following profile.


The matching structure has the following fields :

profile_vertex    A vertex on the profile for which this represents
                    part of the mapping.

matched_vertex    The corresponding vertex on the following profile.

                    If there are guide wires for the loft and the geometry
                    of profile_vertex is coincident with a vertex geometry
                    of a guide wire, then the geometry of matched_vertex
                    is required to be also coincident with a vertex geometry
                    of the same guide wire. The coincidences are measured
                    subject to relevant vertex tolerances.
