# Problem in BRepExtrema_DistShapeShape
#
# This script tries to reproduce the bug in BRepExtrema_DistanceSS class reported
# by Rob Bacnrach on OCCT Forum: http://www.opencascade.org/org/forum/thread_23040
# (when first shape is edge and second is vertex, the points are returned
# for the solutions are swapped)
