Example 3/33/anisotropic-diffusion: Solving Transient Anisotropic Diffusion in Parallel with LibMesh

This example shows how a simple, transient orthotropic scalar diffusion system with constant coefficients can be solved in parallel with libMesh. The initial condition is given, and the solution is advanced in time with a standard implicit time-stepping strategy. The orientation of the orthotropic material structure is defined in the way that CMISS has historically defined such structures in terms of Euler (or really Cardan) rotations from element reference coordinates with fibre, imbrication, and sheet angles.
