40 * Revision 1.4 2014/10/13 08:53:26 j_novak
41 * Lorene classes and functions now belong to the namespace Lorene.
42 *
43 * Revision 1.3 2014/10/06 15:16:06 j_novak
44 * Modified #include directives to use c++ syntax.
45 *
46 * Revision 1.2 2008/08/19 06:42:00 j_novak
47 * Minor modifications to avoid warnings with gcc 4.3. Most of them concern
48 * cast-type operations, and constant strings that must be defined as const char*
49 *
50 * Revision 1.1 2007/12/11 15:42:23 jl_cornou
51 * Premiere version des fonctions liees aux polynomes de Jacobi(0,2)
52 *
53 * Revision 1.2 2004/11/23 15:16:01 m_forot
54 *
55 * Added the bases for the cases without any equatorial symmetry
56 * (T_COSSIN_C, T_COSSIN_S, T_LEG, R_CHEBPI_P, R_CHEBPI_I).
