<h2>Propagation of Node Distribution on Opposite Edges</h2>
<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.
