* $Log: visu_evol.C,v $
* Revision 1.5 2014/10/13 08:53:56 j_novak
* Lorene classes and functions now belong to the namespace Lorene.
*
* Revision 1.4 2014/10/06 15:09:44 j_novak
* Modified #include directives to use c++ syntax.
*
* Revision 1.3 2004/06/24 00:07:28 e_gourgoulhon
* Introduced the reference 'field' and string 'fieldname' for
* a easier selection of the field to be visualized.
* Better determination of the max of the field.
*
* Revision 1.2 2004/06/02 21:34:39 e_gourgoulhon
* Added creation of file anime.dxcont for OpenDX.
