* added allow traversal flag * Added test to verify a single router connection that is marked untraversable fails path creating * Updated default cost to be one step above the threshold to avoid overflow. * Updated checks to only care about middle routers. Fixed relevant unit tests and added test with untraversable middle router. * Refactor allowTraversal to be flipped to noTraversal * default noTraversal to false
