* $Log: binhor_viriel.C,v $
* Revision 1.5 2014/10/13 08:52:42 j_novak
* Lorene classes and functions now belong to the namespace Lorene.
*
* Revision 1.4 2014/10/06 15:13:01 j_novak
* Modified #include directives to use c++ syntax.
*
* Revision 1.3 2007/04/13 15:28:55 f_limousin
* Lots of improvements, generalisation to an arbitrary state of
* rotation, implementation of the spatial metric given by Samaya.
*
* Revision 1.2 2005/04/08 12:35:07 f_limousin
* Just to avoid warnings...
