* removed Makefile for moench and integrated the build in CMake * broke out tiff reading and writing to its own library * moved tiff includes to include/sls * moved tiffio source to src * removed incorrectly used bps * cleanup and tests for tiffio * removed using namespace std from header * some fixing for moench04 * Program for offline processing renamed Co-authored-by: Anna Bergamaschi <anna.bergamaschi@psi.ch>
