Functions
template<int Dim, unsigned Bits>
std::vector< double >	peclet::amr::lohnerIndicator (const BlockOctree< Dim, Bits > &t, const std::vector< double > &u, double eps=0.01)
	Löhner normalized second-difference indicator E_i ∈ [0,1], per leaf, for scalar u (indexed by leaf slot).
template<int Dim, unsigned Bits>
std::vector< double >	peclet::amr::secondDiffIndicator (const BlockOctree< Dim, Bits > &t, const std::vector< double > &u)
	Raw second-derivative magnitude indicator, per leaf: the L2 norm over axes of the undivided second difference |u₊ − 2u_i + u₋| (so ∝ |∂²u|·h²).
