26  * Revision 1.5 2016/12/05 16:18:10 j_novak
27  * Suppression of some global variables (file names, loch, ...) to prevent redefinitions
28  *
29  * Revision 1.4 2014/10/13 08:53:30 j_novak
30  * Lorene classes and functions now belong to the namespace Lorene.
31  *
32  * Revision 1.3 2014/10/06 15:16:10 j_novak
33  * Modified #include directives to use c++ syntax.
34  *
35  * Revision 1.2 2004/08/24 09:14:44 p_grandclement
36  * Addition of some new operators, like Poisson in 2d... It now requieres the
37  * GSL library to work.
38  *
39  * Also, the way a variable change is stored by a Param_elliptic is changed and
40  * no longer uses Change_var but rather 2 Scalars. The codes using that feature
41  * will requiere some modification. (It should concern only the ones about monopoles)
42  *
43  * Revision 1.1 2004/06/22 08:49:58 p_grandclement
44  * Addition of everything needed for using the logarithmic mapping
45  *
