changed so that all files have 755 (-rwxr-xr-x) permissions in source/libcheetah/src/ and source/libcheetah/include/
added the peakDetect class, which implements peak detection for C-arrays. This is useful for common-mode determination from intensity histograms
unified indentation in peakDetect.cpp and peakDetect.h to use 4-space indentation
implemented common-mode algorithm for pnCCD based on peak-finding (using the PeakDetect class) on the intensity histograms for each ASIC. The common-mode correction is only activated if cmModule=1 and detectorType=pnccd
added case sellberg to upload script (syncs with davinci)
