DSLHyPE time step kernels.

The two functions below are never executed as Python. DSLHyPE parses their source (exahype2.api.dslhype.Parser) and translates them into the C++ time step kernels (RusanovWithExplicitEuler.__create_time_step_functions()). They hence refer to symbols that the parser sets rather than Python imports:

• Template parameters: NV, H, NumberOfUnknowns, NumberOfAuxiliaryVariables.
• Functors for the non-stateless code: flux, nonconservativeProduct, volumetricSource, maxEigenvalue.
• loopParallelism (peano4::utils::LoopPlacement) for loop parallelisation.
