 * Revision 1.7  2014/10/13 08:52:33  j_novak
 * Lorene classes and functions now belong to the namespace Lorene.
 *
 * Revision 1.6  2014/10/06 15:09:39  j_novak
 * Modified #include directives to use c++ syntax.
 *
 * Revision 1.5  2004/03/22 13:12:40  j_novak
 * Modification of comments to use doxygen instead of doc++
 *
 * Revision 1.4  2003/11/06 14:43:37  e_gourgoulhon
 * Gave a name to const arguments in certain method prototypes (e.g.
 * constructors) to correct a bug of DOC++.
 *
 * Revision 1.3  2002/10/16 14:36:28  j_novak
 * Reorganization of #include instructions of standard C++, in order to
 * use experimental version 3 of gcc.
 *
 * Revision 1.2  2002/06/17 14:05:16  j_novak
 * friend functions are now also declared outside the class definition
