Class
    Foam::eTabulatedThermo

Description
    Internal energy based thermodynamics package using uniform tabulated
    data for internal energy and heat capacity vs pressure and temperature.

Usage

    \table
        Property    | Description
        Hf          | Heat of formation
        Sf          | Standard entropy
        Es          | Sensible internal energy vs pressure and temperature table
        Cv          | Specific heat capacity vs pressure and temperature table
    \endtable

    Example of the specification of the thermodynamic properties:
    \verbatim
    thermodynamics
    {
        Hf              0;
        Sf              0;
