29 * Revision 1.6 2016/12/05 16:17:46 j_novak
30 * Suppression of some global variables (file names, loch, ...) to prevent redefinitions
31 *
32 * Revision 1.5 2014/10/13 08:52:42 j_novak
33 * Lorene classes and functions now belong to the namespace Lorene.
34 *
35 * Revision 1.4 2014/10/06 15:13:01 j_novak
36 * Modified #include directives to use c++ syntax.
37 *
38 * Revision 1.3 2007/04/13 15:28:55 f_limousin
39 * Lots of improvements, generalisation to an arbitrary state of
40 * rotation, implementation of the spatial metric given by Samaya.
41 *
42 * Revision 1.2 2005/04/08 12:35:07 f_limousin
43 * Just to avoid warnings...
44 *
