tetahedron FEM can report stress and strain tensors
Optimizations in FEM functions - now returning stiffness matrices by reference
Improved new flags for visualization of ChTriangleMeshShape
Improved visualization of FEM meshes in Irrlicht unit. Not yet complete, but enough to show meshes in wireframe, shaded, falsecolour shaded, etc.
Supported: thetahedrons 4 nodes, hexahedrons (partially - the Von Mises stress strains must be implemented).
To be completed.
Improed demo_FEMvisualize.cpp, to test new features of the FEM visualization
