 * Revision 1.8  2023/06/28 10:04:32  j_novak
 * Use of C++ strings and flows instead of C types.
 *
 * Revision 1.7  2016/12/05 16:17:44  j_novak
 * Suppression of some global variables (file names, loch, ...) to prevent redefinitions
 *
 * Revision 1.6  2014/10/13 08:52:39  j_novak
 * Lorene classes and functions now belong to the namespace Lorene.
 *
 * Revision 1.5  2014/10/06 15:12:57  j_novak
 * Modified #include directives to use c++ syntax.
 *
 * Revision 1.4  2013/01/11 08:20:11  j_novak
 * New radial spectral bases with Legendre polynomials (R_LEG, R_LEGP, R_LEGI).
 *
 * Revision 1.3  2007/12/11 15:28:09  jl_cornou
 * Jacobi(0,2) polynomials partially implemented
 *
 * Revision 1.2  2004/11/23 15:08:01  m_forot
 * Added the bases for the cases without any equatorial symmetry
 * (T_COSSIN_C, T_COSSIN_S, T_LEG, R_CHEBPI_P, R_CHEBPI_I).
