//
// ScalerScalerEvtHandler
//
// Event handler for Hall A scalers (THaScalerEvtHandler)
// R. Michaels, Sept, 2014
//
// Lineage:
// - Based on TriScalerEvtHandler for tritium experiments (Hanjie Liu, UMass)
// - Adapted for SBS experiments (David Flay, JLab)
//
// This class does the following
// For a particular set of event types (here, event type 140)
// decode the scalers and put some variables into global variables.
// The global variables can then appear in the Podd output tree T.
// In addition, a tree "TS" is created by this class; it contains
// just the scaler data by itself. Note, the "fName" is concatenated
// with "TS" to ensure the tree is unqiue; further, "fName" is
// concatenated with the name of the global variables, for uniqueness.
// The list of global variables and how they are tied to the
// scaler module and channels is in the scaler.map file, or could
// be hardcoded here.
// NOTE: if you don't have the scaler map file (e.g. db_LeftScalevt.dat)
// there will be no variable output to the Trees.
//
// To use in the analyzer, your setup script needs something like this
// gHaEvtHandlers->Add (new LHRSScalerEvtHandler("Left","HA scaler event type 140"));
//
// To enable debugging you may try this in the setup script
//
// LHRSScalerEvtHandler *lscaler = new LHRSScalerEvtHandler("Left","HA scaler event type 140");
// lscaler->SetDebugFile("LeftScaler.txt");
// gHaEvtHandlers->Add (lscaler);
