351 When an histogram is created, a reference to it is automatically added to the list of in-memory objects for the current file or directory. This default behaviour can be changed by:
353 h->SetDirectory(0); for the current histogram h
354 TH1::AddDirectory(kFALSE); sets a global switch disabling the reference
356 When the histogram is deleted, the reference to it is removed from the list of objects in memory. When a file is closed, all histograms in memory associated with this file are automatically deleted.
