Functions
template<typename Strategy>
std::expected< backend::mfem::Inverse, Failure >	serif::solver::preconditioner::computations::invert_matrix (std::shared_ptr< const ::mfem::SparseMatrix > matrix, const Strategy &strategy)
	Invert an assembled selected matrix with the chosen dense, sparse direct or AMG backend.
template<typename Row, typename Field, typename Strategy>
auto	serif::solver::preconditioner::computations::inverse (const BlockPreconditioner< Row, Field, Strategy > &choice)
	Declare only the numerical inputs required by this chosen inverse.

Variables
template<typename Strategy>
constexpr bool	serif::solver::preconditioner::computations::needs_diagonal = std::same_as<Strategy, strategies::inverse::Diagonal>
	Identify the inverse strategies whose setup consumes a physical diagonal.
template<typename Strategy>
constexpr bool	serif::solver::preconditioner::computations::needs_matrix
	Identify strategies requiring an explicitly assembled selected matrix.
