Use LazyOuterProduct to construct multi-dimensional quadratures. This change allwed to: - Replace the types Quadrature and InverseQuadrature by functions returning outer products of the 1D operators. - Avoid convoluted naming of types. DiagonalInnerProduct is now renamed to DiagonalQuadrature, similarly for InverseDiagonalInnerProduct.
