Bi-Directional relationships throws RuntimeException

[GoogleCodeExporter]

I've used the the following code in the webService:

class diagram Sample {
   class Car {
      1->3(Mirror);
   }

   class Mirror {
      1->1(Car)
   }
}

And got the following exception:

    org.modsl.core.agt.layout.sugiyama.SugiyamaLayoutVisitor.topologicalSort(SugiyamaLayoutVisitor.java:163)

r823 somewhat improves the situation. Topological sorting no longer fails for 
cycles,
including bi-directional relationship. r824 has additional unit tests to support
that. Still need to work on the rendering part of the bi-directional 
relationship to
avoid edge overlap.
