* $Log: eos_bf_file.C,v $
* Revision 1.11 2015/06/11 14:41:59 a_sourie
* Corrected minor bug
*
* Revision 1.10 2015/06/10 14:39:17 a_sourie
* New class Eos_bf_tabul for tabulated 2-fluid EoSs and associated functions for the computation of rotating stars with such EoSs.
*
* Revision 1.9 2014/10/13 08:52:52 j_novak
* Lorene classes and functions now belong to the namespace Lorene.
*
* Revision 1.8 2014/10/06 15:13:06 j_novak
* Modified #include directives to use c++ syntax.
*
* Revision 1.7 2014/04/25 10:43:51 j_novak
* The member 'name' is of type string now. Correction of a few const-related issues.
*
* Revision 1.6 2008/08/19 06:42:00 j_novak
* Minor modifications to avoid warnings with gcc 4.3. Most of them concern
* cast-type operations, and constant strings that must be defined as const char*
*
* Revision 1.5 2003/12/05 15:09:47 r_prix
* adapted Eos_bifluid class and subclasses to use read_variable() for
* (formatted) file-reading.
*
* Revision 1.4 2002/10/16 14:36:34 j_novak
* Reorganization of #include instructions of standard C++, in order to
* use experimental version 3 of gcc.
*
* Revision 1.3 2002/01/11 14:09:34 j_novak
* Added newtonian version for 2-fluid stars
*
* Revision 1.2 2001/12/04 21:27:53 e_gourgoulhon
*
* All writing/reading to a binary file are now performed according to
* the big endian convention, whatever the system is big endian or
* small endian, thanks to the functions fwrite_be and fread_be
*
* Revision 1.1.1.1 2001/11/20 15:19:27 e_gourgoulhon
* LORENE
*
* Revision 1.1 2001/06/21 15:22:15 novak
* Initial revision
