C++ API

The DiFfRG C++ library is the core of the framework. A physics Model (inheriting AbstractModel via CRTP) is paired with a Discretization (CG/DG/DDG/LDG FEM or FV); an Assembler computes residuals and Jacobians, a Timestepper evolves the solution in RG time, and Output modules write CSV/HDF5/VTK results.
