 * $Log: mtbl.C,v $
 * Revision 1.10  2016/12/05 16:17:59  j_novak
 * Suppression of some global variables (file names, loch, ...) to prevent redefinitions
 *
 * Revision 1.9  2014/10/13 08:53:08  j_novak
 * Lorene classes and functions now belong to the namespace Lorene.
 *
 * Revision 1.8  2014/10/06 15:13:15  j_novak
 * Modified #include directives to use c++ syntax.
 *
 * Revision 1.7  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 1.6  2008/02/18 13:53:40  j_novak
 * Removal of special indentation instructions.
 *
 * Revision 1.5  2002/10/16 14:36:43  j_novak
 * Reorganization of #include instructions of standard C++, in order to
 * use experimental version 3 of gcc.
 *
 * Revision 1.4  2002/09/06 15:37:46  e_gourgoulhon
 * Performed a forgotten replacement
 *  t = new (Tbl *[nzone])  -->   t = new Tbl*[nzone]
 * to ensure compatibility with the xlC_r compiler on IBM Regatta
 *
 * Revision 1.3  2002/05/07 07:36:03  e_gourgoulhon
 * Compatibilty with xlC compiler on IBM SP2:
 *    suppressed the parentheses around argument of instruction new:
 *  e.g.   t = new (Tbl *[nzone])  -->   t = new Tbl*[nzone]
 *
 * Revision 1.2  2001/12/04 21:27:54  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 2.10  2000/08/16  10:30:04  eric
 * Suppression du membre dzpuis.
 *
 * Revision 2.9  1999/11/23  13:33:04  eric
 *  Le constructeur Tbl::Tbl(const Grille3d* ) est devenu Tbl::Tbl(const Grille3d& ).
 *
 * Revision 2.8  1999/10/29  15:06:24  eric
 * Suppression des fonctions membres min() et max():
 * elles deviennent des fonctions externes.
 *
 * Revision 2.7  1999/10/18  15:16:05  eric
 * *** empty log message ***
 *
 * Revision 2.6  1999/10/18  15:08:22  eric
 * La fonction membre annule() est rebaptisee annule_hard().
 * Introduction de la fonction membre annule(int, int).
 *
 * Revision 2.5  1999/10/01  12:35:54  eric
 * Ajout de la fonction affiche_seuil.
 *
 * Revision 2.4  1999/10/01  10:08:41  eric
 * Depoussierage.
 * Documentation.
 *
 * Revision 2.3  1999/03/02  16:26:26  eric
 * Modif des indentations dans <<
 *
 * Revision 2.2  1999/03/02  15:34:08  eric
