//============================================================================
// 
// Author : Matteo Bedognetti <matteo.bedognetti@cern.ch.>
// Changes:
//
// Store trigger counts for specific chains in the DAOD's MetaData.
// This allows it to store information about triggers upon which events are NOT selected during the derivation
//
// Job options:
// - TriggerList   -- a vector containing all triggers to store as strings
// - FolderName -- Is supposed to be the derivation name (some convention I guess)
// - TrigDecisionTool -- if one wants to pass this a specific TrigDecisionTool
//
