Functions
template<typename HS, typename T, bool BasedOnMap>
auto	triqs::hilbert_space::make_zero_state (state< HS, T, BasedOnMap > const &phi)
	Create a zero state in the same Hilbert (Fock) space as the given state.
template<typename HS, typename T, bool BasedOnMap>
std::ostream &	triqs::hilbert_space::operator<< (std::ostream &sout, state< HS, T, BasedOnMap > const &psi)
	Write a triqs::hilbert_space::state<HS, T, true> or a triqs::hilbert_space::state<HS, T, false> to a std::ostream.
template<typename TargetState, typename OriginalState>
TargetState	triqs::hilbert_space::project (OriginalState const &psi, hilbert_space const &proj_hs)
	Project a state \( \lvert \psi \rangle \in \mathcal{F}^{(m)} \) to a new Hilbert (Fock) space \(\mathcal{F}' \).
template<typename TargetState, typename OriginalState>
TargetState	triqs::hilbert_space::project (OriginalState const &psi, sub_hilbert_space const &proj_hs)
	Project a state \( \lvert \psi \rangle \in \mathcal{F}^{(m)} \) to a new Hilbert (Fock) subspace \(\mathcal{F}'^{(m')} \).
