    eintSwitch [REAL] [0.0]
        Valid Values: Unconstrained
        a rarely used switch which ensures that internal energy calculations
        maintain sufficient precision. Important only if energyTotal is
        dominated by energyKinetic. If (energyInternal <
        eintSwitch*energyKinetic) then some routines (Eos/Helmholtz,
        Hydro/hy_updateSoln) will NOT calculate energyInternal by subtraction,
        but rather through direct calculation.

        eos_idealGamma for the meaning of the various choices. The choice that
        corresponds most closely to the Sackur-Tetrode equation in physical
        units should be 3, closely followed by 2.

        return in the EOS_TEMP part of eosData, when Eos is called in a mode for
        which EOS_TEMP is an output and different component temperatures can be
        returned. 1 for ion temperature EOS_TEMPION; 2 for electron temperature
        EOS_TEMPELE; 3 for radiation temperature EOS_TEMPRAD; 0 for the
        temperature that would result in the same specific internal energy as
        given if all components where equilibrated at the same temperature,
