32  * $Log: map_af_elliptic_2d.C,v $
33  * Revision 1.3 2016/12/05 16:17:56 j_novak
34  * Suppression of some global variables (file names, loch, ...) to prevent redefinitions
35  *
36  * Revision 1.2 2014/10/13 08:53:02 j_novak
37  * Lorene classes and functions now belong to the namespace Lorene.
38  *
39  * Revision 1.1 2004/08/24 09:14:42 p_grandclement
40  * Addition of some new operators, like Poisson in 2d... It now requieres the
41  * GSL library to work.
42  *
43  * Also, the way a variable change is stored by a Param_elliptic is changed and
44  * no longer uses Change_var but rather 2 Scalars. The codes using that feature
45  * will requiere some modification. (It should concern only the ones about monopoles)
