 * $Log: sym_tensor_tt.C,v $
 * Revision 1.8  2016/12/05 16:18:17  j_novak
 * Suppression of some global variables (file names, loch, ...) to prevent redefinitions
 *
 * Revision 1.7  2014/10/13 08:53:43  j_novak
 * Lorene classes and functions now belong to the namespace Lorene.
 *
 * Revision 1.6  2014/10/06 15:13:19  j_novak
 * Modified #include directives to use c++ syntax.
 *
 * Revision 1.5  2005/04/01 14:28:32  j_novak
 * Members p_eta and p_mu are now defined in class Sym_tensor.
 *
 * Revision 1.4  2004/03/30 14:01:19  j_novak
 * Copy constructors and operator= now copy the "derived" members.
 *
 * Revision 1.3  2004/03/03 13:16:21  j_novak
 * New potential khi (p_khi) and the functions manipulating it.
 *
 * Revision 1.2  2004/01/04 20:52:45  e_gourgoulhon
 * Added assignement (operator=) to a Tensor_sym.
