//
// 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_rawloader.C
// AliEveTRDLoader *raw = trd_rawloader(filename);
// raw->NextEvent();
// 
// Caution:
// In order to update the screen one has to go to GLViewer 
// and click the UpdateScene button after each NextEvent().
