 * Revision 1.8  2016/12/05 16:18:11  j_novak
 * Suppression of some global variables (file names, loch, ...) to prevent redefinitions
 *
 * Revision 1.7  2014/10/13 08:53:33  j_novak
 * Lorene classes and functions now belong to the namespace Lorene.
 *
 * Revision 1.6  2014/10/06 15:13:15  j_novak
 * Modified #include directives to use c++ syntax.
 *
 * Revision 1.5  2007/05/06 10:48:13  p_grandclement
 * Modification of a few operators for the vorton project
 *
 * Revision 1.4  2004/01/15 09:15:38  p_grandclement
 * Modification and addition of the Helmholtz operators
 *
 * Revision 1.3  2003/12/11 16:12:10  e_gourgoulhon
 * Changed sqrt(2) to sqrt(double(2)).
 *
 * Revision 1.2  2003/12/11 15:57:27  p_grandclement
 * include stdlib.h encore ...
 *
 * Revision 1.1  2003/12/11 14:48:50  p_grandclement
