* $Log: map_log_elliptic.C,v $
* Revision 1.6 2014/10/13 08:53:05 j_novak
* Lorene classes and functions now belong to the namespace Lorene.
*
* Revision 1.5 2014/10/06 15:13:13 j_novak
* Modified #include directives to use c++ syntax.
*
* Revision 1.4 2007/01/16 15:08:07 n_vasset
* New constructor, usn Scalar on mono-domain angular grid for boundary,
* for function sol_elliptic_boundary()
*
* Revision 1.3 2005/06/09 07:57:32 f_limousin
* Implement a new function sol_elliptic_boundary() and
* Vector::poisson_boundary(...) which solve the vectorial poisson
* equation (method 6) with an inner boundary condition.
*
* Revision 1.2 2004/08/24 09:14:42 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)
*
* Revision 1.1 2004/06/22 08:49:58 p_grandclement
* Addition of everything needed for using the logarithmic mapping
*
* Revision 1.4 2004/03/17 15:58:48 p_grandclement
