+<b>Propagation of Node Distribution on Opposite Edges</b> allows to propagate
+distribution of nodes onto an opposite edge. If a local hypothesis and
+propagation are defined on an edge of a quadrangular face, the
+opposite edge will have the same number of nodes and the same
+relations between segment lengths, unless another hypothesis
+has been locally defined on the opposite edge.
