Draft: Adapting BHE process to soil freezing

Christian Silbermann requested to merge cbsilver/ogs:MPL_Freezing_BHE into master

The HeatTransportBHE process is modified in order to take into account soil freezing. Therefore, the soil is now considered as a mixture of three phases:

  • Porous phase (the solid)
  • Liquid phase (e.g. water)
  • Frozen liquid phase (e.g. ice)

The effective (apparent) heat capacity includes the latent heat contribution from the phase change of the liquid/frozen pore phase. The HeatTransportBHE process was slightly modified to make use of the effective properties (fractional averages).
