* added a new material parameter "surfaceTransmissivity" (default value 1.0) which allows to change the transmissivity of the material surface between 0 and 1
* now complaining when encountering an unknown nonlocal parameter in material.config * use same error ID for all material parameters out of bounds * symmetric flux calculation in side dotState can now be omitted (because of new treatment of periodicity) * switching back to "local flux balance" (add leaving and entering fluxes at central MP, don't touch neighbor) instead of "flux distribution" (subtract leaving fluxes from central MP and add them at neighboring MP). This has the advantage that there is almost no need for CRITICAL statements in parallelization, so hopefully this results in some speed up.
