Detailed Description

MeshViz Defines a quadrangle cell of a surface mesh.

A quadrangle cell is not necessarily a square, it can be a rectangle or a lozenge.

Nodes and edges are numbered as following :

             3-----------2   edge 0 = 01
             |           |   edge 1 = 12
             |           |   edge 2 = 23
             |           |   edge 3 = 30
             |           |
             |           |
             0-----------1
