// Reads in an input file specifying the triggers we're interested in.
// The input file has the format:
//  <trigger name>   <trigger object name>   <trigger object leg #>
//
// A trigger with multiple objects will have multiple entries with the same <trigger name> but
// one entry for each <trigger object name>.
//
// The trigger object leg numbering is to account for the possibility that a particular object of
// the trigger can evolve and obtain a different trigger object name, but we still want this to
// be associated with the same leg (e.g. the trailing electron in a dielectron trigger)
