calculation. This is a reclarification of the reference state thermo calculations for individual species, and an expansion to handle liquid phase thermo needs. There is now a virtual base class for the calculation of reference state thermo functions for individual species. It is called SpeciesThermoInterpType. There is also a class which allows for a complete general calculation of the reference state species thermo for a phase, GeneralSpeciesThermo. Some of this new functionality may be relegated to ifdef blocks in the future to limit the amount of code for users who don't need the new functionality.
