/**
* \class Element2DC0LinearQuadrilateralStress
* \ingroup ITKFEM
* \brief 4-noded finite element class in 2D space.
*
* The ordering of the nodes is counter clockwise. That is the nodes
* should be defined in the following order:
*
* 3 (0,1) 2 (1,1)
* *------------------------*
* | |
* | |
* | |
* | |
* | |
* | |
* *------------------------*
* 0 (0,0) 1 (0,1)
*
* The constitutive equation used is from the principles of linear elasticity.
* This class combines the geometry of the FE problem defined in
* \link Element2DC0LinearQuadrilateral\endlink
* and the physics of the problem defined in
* \link Element2DStress\endlink
*
