This structure holds an array of matches, each of which describes an
association between a vertex of the given profile of the loft and one
on the immediately following profile.


The matching structure has the following fields :

profile         The profile for which this is a mapping of the vertices
                  onto those of the next profile.

n_matches       The number of matches held in the structure. This must
                  not exceed the number of vertices on the profile.

matches         An array of matches, each of which describes an
                  association between a vertex of the given profile of the
                  loft and one on its immediate following neighbour.
