Quadrangle parameters
-Quadrangle parameters is a general hypothesis for
-Quadrangle (Mapping). This hypothesis gives a possibility
-of using Quadrangle (Mapping) mechanism for faces built on 3 edges.
-The hypothesis requires some vertex to be selected from the face; this vertex will be
-used as degenerated edge. The resulting mesh will include several triangles near this
-vertex. Hypothesis construction and resulting mesh is displayed at the following figures:
