//
// THcScalerEvtHandler
//
// Event handler for Hall C scalers
// E. Brash, June, 2015
// based on THaScalerEvtHandler
// R. Michaels, Sept, 2014
//
// This class does the following
// For a particular set of event types (here, event type 0)
// 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 defined here; eventually this
// will be modified to use a scaler.map file
// NOTE: if you don't have the scaler map file (e.g. Leftscalevt.map)
// there will be no variable output to the Trees.
//
// To use in the analyzer, your setup script needs something like this
// gHaEvtHandlers->Add (new THcScalerEvtHandler("HMS","HC scaler event type 0"));
//
// To enable debugging you may try this in the setup script
//
// THcScalerEvtHandler *hscaler = new THcScalerEvtHandler("HS","HC scaler event type 0");
// hscaler->SetDebugFile("HScaler.txt");
// gHaEvtHandlers->Add (hscaler);
