// How to steer the TRD loaders from a macro
// For the usage of only the TRD data containers and 
// AliEve event loop check the macro "trd_detectors.C"
// 
// Usage:
// .L trd_loader.C
// AliCDBManager *cdb = AliCDBManager::Instance();
// cdb->SetDefaultStorage("local://$ALICE_ROOT/OCDB");
// cdb->SetRun(0)
// AliEveTRDLoader *loader = trd_loader();
// loader->NextEvent();
// loop(loader)
