all automatic generated Streamer()'s are in the *_G__*.cxx dictionary
files. Streamers you see in the source together with the other
class methods are generally modified Streamers. Every class that
you want to write to the DB needs to have a streamer, independent
of inheritance from TObject. This is steered via ClassDef(xxx,1).
