- Add Fourier for lattice. - Add regular_bz_mesh, cyclic_lattice, and their FFT. - rm freq_infty. - The gf can now be evaluated on a tail_view, which result in composing the tail. - Fix the following issue : g(om_) << g(om_ +1) will recompose the tail correctly. - TODO : TEST THIS NEW FEATURE IN DETAIL. - Work on singularity for G(x, omega) - Separate the factory for singularity from the data factory in gf. - overload assign_from_functoin (renamed). - Fix singularity_t and co in the gf (const issue). - Clean tail, add tail_const_view - add m_tail for x -> tail on any mesh - test curry + fourier works on k
