geometry/test/multi/algorithms/overlay/multi_traverse.cpp
Barend Gehrels e71fb07566 Assemble/traverse/enrich: complete update for handling self tangencies 
-> added many testcases

Various updates in testcases for support of open polygons
recursive_boxes.cpp, added triangles as well (dropped corner)
