Added comparater delay scan and analysis

the comparator scan uses Occupancy analysis, which produce OccupancyMap.

Because of several parameter loop and parameter value is similar, I hardcore coded on Occupancy map. This shold be fixed on some day.

In src/scripts, comparatorDelayDataProcess uses Occupancy*.dat data and put them to root file (TTree).

comparatorDelayAnalysis uses data TTree in root file to produce plots, hits vs time, time vs comparator register value.

comparatorDelayMerge does not work currently, but it will merge data which different scan range, scan step.
