Functions
std::expected< Inverse, Failure >	serif::solver::preconditioner::backend::mfem::try_coupled_inverse (Inverse first, Inverse second, TwoBlockCouplings couplings, strategies::coupling::CouplingOrder order)
	Compose two inverses with the requested treatment of their cross couplings.
std::expected< OperatorHandle, Failure >	serif::solver::preconditioner::backend::mfem::try_schur_operator (OperatorHandle retained_diagonal, Inverse eliminated, TwoBlockCouplings couplings)
	Form the retained Jacobian minus its response through a fixed linear eliminated inverse.
