33  * Revision 1.2 2014/10/13 08:53:02 j_novak
34  * Lorene classes and functions now belong to the namespace Lorene.
35  *
36  * Revision 1.1 2004/08/24 09:14:42 p_grandclement
37  * Addition of some new operators, like Poisson in 2d... It now requieres the
38  * GSL library to work.
39  *
40  * Also, the way a variable change is stored by a Param_elliptic is changed and
41  * no longer uses Change_var but rather 2 Scalars. The codes using that feature
42  * will requiere some modification. (It should concern only the ones about monopoles)
