returns Data Loader with specified name

 Adds a data loader

basically the same that GetEvent but do not post data to folders

calls UnloadAll for all base laoders
Unloads everything

changes to proper root  directory and tries to load data from files to folders
 event number is defined in RunLoader

returns:
     0  - in case of no error
     1  - event not found

returns TOP aliroot folder, just a simple interface to AliConfig (gives shorter notation)

get EVENT folder (data that are changing from event to event, even in single run)

returns the folder speciofic to given detector e.g. /Folders/Event/Data

returns pointer to the folder containing modules

changes the root directory in "file" to "dirname" which corresponds to event 'eventno'
in case of success returns the pointer to directory
else NULL

This Method will manage jumping through unix directories in case of
run with more events per run than defined in gAlice

Makes a tree depending on option
   H: - Hits
   D: - Digits
   S: - Summable Digits
   R: - Reconstructed Points (clusters)
   T: - Tracks (tracklets)

 Writes hits

 Writes summable digits

 Returns pointer to an entry in the list of folders pointing to "obj"

Cleans all posted objects == removes from folders and deletes them

 Calling Reload function for all the data loaders

close files for data loaders

sets the event folder

triggers creation of subfolders for a given detector
this method is called when session is read from disk

warning: AliDetector in constructor (not default) calls
creation of folder structure as well (some detectors needs folders
alrady in constructors)

gets the run-loader from event folder

tests the TFile::Option
if file is truncated at opening moment ("recreate", "new" or "create") returns kFALSE;
else kTRUE (means opened with "read" or "update" mode)

adds "dirname" to each file. Dirname should end with "#","/", or ":"

adds the suffix before ".root",
e.g. TPC.Digits.root -> TPC.DigitsMerged.root
made on Jiri Chudoba demand

sets comression level for data defined by di

Cleans all data loaders

 Removes object with "name" from the detector's data folder
 and from the memory

 Returns "true" if the option means also "writable"

 Sets debug level

calls SetTreeAddress for corresponding detector

synchrinizes all writtable files

helper function which returns the folder of name "name" in data folder

these methods are responsible for reading data
 1. Opens the file (accordingly to gAlice->GetEvNumber()/Nevents per File
 2. Changes to proper ROOT directory
 3. Retrives data and posts to folders
options:
   ""       - readonly file
   "update" - update file
   "recreate"

void SetTopFolder(TString& str){}; //Sets root top folder for the run

Opens hits file and jumps to directory cooresponding to current event.
If dir does not exists try to create it
opt is passed to TFile::Open
reads data from the file and posts them into folder
