Detailed Description

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
