The old fluid-specific rhoThermo has been split into a non-fluid
specific part which is still called rhoThermo, and a fluid-specific part
called rhoFluidThermo. The rhoThermo interface has been added to the
solidThermo model. This permits models and solvers that access the
density to operate on both solid and fluid thermophysical models.
The he*Thermo classes have been renamed to match their corresponding
basic thermo classes. E.g., rhoThermo now corresponds to RhoThermo,
rather than heRhoThermo.
Full backward-compatibility is provided which support for both multiComponentMixture and
multiComponentPhaseModel provided but all tutorials have been updated.
Now that the reaction system, chemistry and combustion models are completely
separate from the multicomponent mixture thermophysical properties package that
supports them it is inconsistent that thermo is named reactionThermo and the
name multicomponentThermo better describes the purpose and functionality.
