Class
    Foam::ThermoPhaseModel

Description
    Class which represents a phase with a thermodynamic model. Provides access
    to the thermodynamic variables. Note that the thermo model itself is not
    returned as this class could be substituted in the hierarchy for one which
    mirrors the functionality, but does not include a thermo model; an
    incompressible phase model, for example.
