comparison sbpD2.jl @ 129:1aaeb46ba5f4 cell_based_test

Improve efficiency of apply by the following: - Remove divisions in interior loop by storing and multiplying by the reciprocal of grid spacing instead. - Add @inline to apply(::Laplace - Remove initialization of w = 0 in apply(::Stencil) by manually unrolling first iteration of the loop.
