 * $Log: param_elliptic_2d.C,v $
 * Revision 1.5  2018/11/16 14:34:36  j_novak
 * Changed minor points to avoid some compilation warnings.
 *
 * Revision 1.4  2016/12/05 16:18:14  j_novak
 * Suppression of some global variables (file names, loch, ...) to prevent redefinitions
 *
 * Revision 1.3  2014/10/13 08:53:37  j_novak
 * Lorene classes and functions now belong to the namespace Lorene.
 *
 * Revision 1.2  2014/10/06 15:13:15  j_novak
 * Modified #include directives to use c++ syntax.
 *
 * Revision 1.1  2004/08/24 09:14:49  p_grandclement
 * Addition of some new operators, like Poisson in 2d... It now requieres the
 * GSL library to work.
 *
 * Also, the way a variable change is stored by a Param_elliptic is changed and
 * no longer uses Change_var but rather 2 Scalars. The codes using that feature
 * will requiere some modification. (It should concern only the ones about monopoles)
