Barend Gehrels 3d5906f1e8 [traversal] revised switch detector because could not get previous approach ...

working for the last cases and for newly created connected interior rings. The new approach is much simpler and based
on regions (connected rings, connected via interiors) and works for almost
all cases including newly created connected interiors. Last cases still to
be checked though.

It does not traverse through turns, but instead navigates through rings
