88cb7938 18// Description:
19// This class is responsible for creating folder structure
20// All stuff of aliroot sits in one folder with name defined by
21// fgkTopFolderName data wich do not very trough event to event are
22// sitting in directly in "top folder" all data which changes from
23// event to event are sitting in one folder (which has more subfolders)
24// Idea is to have more than one event in folder structure which allows
25// usage of standard procedures in merging
26// Add(AliDetector*) calls Add(AliModule*) as AliDetector is a AliModule
27// as well and should be listed in module list
