-Returns an equivalence graph of the collation, in which all readings
-related via a 'colocated' relationship are transformed into a single
-vertex. Can be used to determine the validity of a new relationship. The
-mapping between equivalence vertices and reading IDs will be stored in the
-hash whose reference is passed as readingmap. For a subset of the graph,
-pass in a start and/or an ending rank (this only works if L<calculate_ranks>
-has been called at least once.)
-
-It is also possible to pass in a test relationship in @testvector, and get
-the resulting equivalence graph before the relationship has been made.
