 * Revision 1.16  2015/08/04 14:41:28  j_novak
 * Back to previous version for Eos_CompOSE. Enthalpy-consistent EoS can be accessed using Eos_consistent class (derived from Eos_CompOSE).
 *
 * Revision 1.15  2015/01/27 14:22:38  j_novak
 * New methods in Eos_tabul to correct for EoS themro consistency (optional).
 *
 * Revision 1.14  2014/10/13 08:52:34  j_novak
