introduces individual diffusivities for product and fuel in the parameters struct, this state was used for the latest high res 7.1 cm flame, that is stable

introduces new Parameters for SpongeLayer and ForcingScheme, gives reasonable results for 7.1cm Flame, but chrashes after 150000 dt at the interface
