* \class Element2DC0QuadraticTriangularStrain
* \brief 6-noded finite element class in 2D space for linear elasticity problem
* that defines a triangle element.
*
*
* The ordering of the nodes is counter clockwise. That is the nodes
* should be defined in the following order:
*
* (0,1)
* 2
* *
* |\
* | \
* | \
*(0,0.5) 5 * * 4 (0.5, 0.5)
* | \
* | \
* *-----*-----*
* 0 3 1
* (0,0) (0,0.5) (0,1)
*
* * This class combines the geometry of the FE problem defined in
* \link Element2DC0QuadraticTriangular\endlink
* and the physics of the problem defined in
* \link Element2DStrain\endlink
*
* \sa Element2DC0LinearTriangularStress
*
* This element is combined from Element2DC0LinearTriangular and Element2DStrain.
* \ingroup ITKFEM
