* Revision 1.6 2014/10/13 08:53:02 j_novak
* Lorene classes and functions now belong to the namespace Lorene.
*
* Revision 1.5 2005/08/25 12:14:09 p_grandclement
* Addition of a new method to solve the scalar Poisson equation, based on a multi-domain Tau-method
*
* Revision 1.4 2004/05/06 15:25:39 e_gourgoulhon
* The case dzpuis=5 with null value in CED is well treated now.
*
* Revision 1.3 2004/02/20 10:55:23 j_novak
* The versions dzpuis 5 -> 3 has been improved and polished. Should be
* operational now...
*
* Revision 1.2 2004/02/06 10:53:52 j_novak
* New dzpuis = 5 -> dzpuis = 3 case (not ready yet).
*
* Revision 1.1.1.1 2001/11/20 15:19:27 e_gourgoulhon
* LORENE
*
* Revision 1.9 2000/05/22 13:46:48 phil
* ajout du cas dzpuis = 3
*
* Revision 1.8 2000/02/09 14:44:24 eric
* Traitement de dzpuis ameliore.
*
* Revision 1.7 1999/12/22 16:37:10 eric
* Ajout de pot.set_dzpuis(0) a la fin.
*
* Revision 1.6 1999/12/22 15:11:03 eric
* Remplacement du test source.get_mp() == this par
* source.get_mp()->get_mg() == mg
* (idem pour pot),
* afin de permettre l'appel par Map_et::poisson.
*
* Revision 1.5 1999/12/21 13:02:37 eric
* Changement de prototype de la routine poisson : la solution est
* desormais passee en argument (et non plus en valeur de retour)
* pour s'adapter au prototype general de la fonction virtuelle
* Map::poisson.
*
* Revision 1.4 1999/12/21 10:06:29 eric
* Ajout de l'argument (muet) Param&.
