Fixed a	bug so that useCorrelation, usePolarizationCorrection and useSolidAngleCorrection can be used without saving individual hits, changed so that sumCorrelation works properly without saving binary files
implemented an ini-file switch called correlationOutput to control what kind of output to be saved from the correlation algorithm, implemented the interface for switches to control normalization algorithm and Qscale algorithm in the correlation as well (the functionality will be implemented in the next update)
