Functions
template<int N = 0, nda::MemoryArray A>
auto	triqs::gfs::flatten_2d (A const &v)
	Flatten an array into two dimensions, keeping one dimension and collapsing the rest.
template<int N = 0, MemoryGf G>
auto	triqs::gfs::flatten_gf_2d (G const &g)
	Flatten a Green's function into a single-mesh, tensor-valued Green's function.
template<int N = 0>
void	triqs::gfs::unflatten_2d (nda::MemoryArray auto &&out, nda::MemoryArray auto const &afl)
	Inverse of triqs::gfs::flatten_2d: scatter a two-dimensional array back into a higher-rank array.
template<int N = 0, MemoryGf Gfl>
void	triqs::gfs::unflatten_gf_2d (MemoryGf auto &g, Gfl const &gfl)
	Inverse of triqs::gfs::flatten_gf_2d: scatter a flattened Green's function back into a higher-rank one.
