Draft: Non isothermal richards flow mechanics
This MR presents the implementation of classes of non isothermal Richards flow mechanics. The theory and the description of the benchmark can be found on overleaf (click).
The CRTP (Curiously recurring template pattern) programming idiom was employed to enable a flexible framework for different coupling schemes. So far the local assembler for the staggered coupling of T-H-M was created.
For this implementation, there are large amount of changes concerning to the global variable arguments, which is split to !3082 (merged).
