Title: add histograms into SignalRegion

Histograms of "rawE" and "wgtE" before & after PU subtraction are filled and stored in output .root files.
The SignalRegion class can be used by:
SignalRegion SignalEnergy(outFolder, nLayers, nEvts, geomConv, puDensity);
SignalEnergy.initialise(lSimTree, lRecTree, mycalib, outputFile);
SignalEnergy.fillHistograms();
