 * Revision 1.6  2023/06/28 10:04:32  j_novak
 * Use of C++ strings and flows instead of C types.
 *
 * Revision 1.5  2016/12/05 16:17:44  j_novak
 * Suppression of some global variables (file names, loch, ...) to prevent redefinitions
 *
 * Revision 1.4  2014/10/13 08:52:39  j_novak
 * Lorene classes and functions now belong to the namespace Lorene.
 *
 * Revision 1.3  2014/10/06 15:12:57  j_novak
 * Modified #include directives to use c++ syntax.
 *
 * Revision 1.2  2012/01/17 14:44:27  j_penner
 * Modified phi variables to only use 16 integers in arrays
 *
 * Revision 1.1  2003/10/19 19:49:40  e_gourgoulhon
