Solvent defined by database

Defines the solvent properties using an external database. An example is given below:

EOS SOLVENT
  DATABASE solvent_dbase.dat
END

The database in the file must have the format specified in the EOS properties database and contains all the properties needed for the solvent (density, viscosity, enthalpy). For COMP3 and COMP4 modes that model solubility effects, the fugacity is also required.
