Disabling Histogram Monitoring

Histogram monitoring may be disabled during on-line running of QOD. The program hist_toggle.f90 allows you to enter a single histogram, range of histograms, or hot wire to turn off. These histogram ranges are saved to a file (Disable_hists.dat) which communicates with QOD. Changes may be made to this file during an analysis, and will take effect with analysis of the next Sample. To re-enable histograms simply run hist_toggle.f90 and choose to replace Disable_hists.dat and then exit the program. It is important to note that this file is not destroyed at the end of the run, so the user should enable all histograms before analyzing the next run.
