Detailed Description

Mixed-hybrid model of linear Darcy flow, possibly unsteady.

Abstract class for various implementations of Darcy flow. In future there should be one further level of abstraction for general time dependent problem.

maybe TODO: split compute_one_step to : 1) prepare_next_timestep 2) actualize_solution - this is for iterative nonlinear solvers
