findShortestPathway

public static Pathway findShortestPathway(Schema schema1,
                                          Schema schema2)

                                          NotFoundException

Find the shortest path containing the fewest number of steps between two schemas. Note that this might not be the best path to use, since it might contain extend and contract transformations, where a longer path might not contain extend and contract transformations.
