* \class Element3DStrain
* \brief Class that is used to define linear elasticity problem in 3D space.
*
* This class only defines the physics of the problem. Use his class together
* with element classes that specify the geometry to fully define the element.
*
* This class defines the physics to define element strain.
*
* You can specify one template parameter:
*
* TBaseClass - Class from which Element3DStrain is derived. TBaseClass must
* be derived from the Element base class. This enables you
* to use this class at any level of element definition.
* If not specified, it defaults to the Element base class.
