class AliXRDPROOFtoolkit: public TObject

 Create a chain of files using the file 'fileIn' as input list
 where one line per root file is expected

 treeName : Name of the tree
 fName    : file name inside of a zip file, will add '#fName'
            to the file name
 maxFiles : maximum number of files in the chain
            -1 (default) add all possible files starting from 'startFile'
 startFile: position of the first file, starting with 0

 Create a TDSet - files are in random order

 filein    - input list text file
 treename  - containg tree
 maxFiles  - maximum number of files included

 Create the TDSet out of list
 filein    - input list text file
 treename  - containg tree
 maxFiles  - maximum number of files included

 Create a TDSet - files are in random order

 filein    - input list text file
 treename  - containg tree
 maxFiles  - maximum number of files included

 Check the tree in file
 fileName   - the name of the file with tree
 treeName   - the name of file
 debugLevel - 0 check the existance of the file -  1 make loop over entries
 branchName - if debugLevel>0 the branch is chcecked
              if brnachName =0 the content of full tree is chcecked
 return value = 0 - Check things  OK
               -1 - file not exist or not accesible
               -2 - file is zombie
		   -3 - tree not present
               -4 - branch not present

 Filter the list
 inputList - list of original file names
 fileList  - list of file to be checked
           - 0 - fileName
           - 1 - treeName (if * not checked)
           - 2 - fileName

 checkLevel - 0 - check only existance of the files and tree's +
                  simple file corruption
            > 1 - check the content of the tree -
                  (can crash as there do not exest exception handling in ROOT)
 Output -  two streams are created - file with good entries
 "%s.Good a,d file with bad entries %s.Bad
EXAMPLE:
 AliXRDPROOFtoolkit::FilterList("ppgrid2.txt","AliESDs.root esdTree AliESDfriends.root * Kinematics.root *",1)

 Filter the list
 inputList - list of original file names
 fileList  - list of file to be checked
           - 0 - fileName
           - 1 - treeName (if * not checked)
           - 2 - fileName

 checkLevel - 0 - check only existance of the files and tree's +
                  simple file corruption
            > 1 - check the content of the tree -
                  (can crash as there do not exest exception handling in ROOT)
 Output -  two streams are created - file with good entries
 "%s.Good a,d file with bad entries %s.Bad
EXAMPLE:
 AliXRDPROOFtoolkit::FilterList("ppgrid2.txt","AliESDs.root esdTree AliESDfriends.root * Kinematics.root *",1)

 idir  - input directory
 odir  - output directory
 files - the list of files to be coppied
 zip   - not supported yet

 Example :

 idir ="root://gsiaf.gsi.de:1094//sma/sim/v4-05-Rev-03/pp/0000";
 odir ="root://lxgrid2.gsi.de:1094//miranov/test/pp/0000";
 char *files="AliESDs.root AliESDfriend.root Kinematics.root";

 Join together several tree according to the index

 Parameters:
 Output:
     outputFile : name of the output file
     outputTree : name of the output Tree
     indexName  : name of the branch to be used as an index
 Input:
     inputTrees : decription of the input trees setup

    Example usage:

    AliXRDPROOFtoolkit::JoinTreesIndex("outAll.root","joinAll","run","1#CPass1#run#tpcQA#TPCCPass1.root+1#VPass1#run#tpcQA#TPCVPass1.root+1#Pass1#run#tpcQA#TPCPass1.root+0#DAQ#run#joinTree#fproductionJoin.root+0#C#run#dcs#OCDBscan.root+0#CE#run#Fits#CEtrend.root");
    ==>
    Combine information form the Cpass1,VPass, and Pass1QA, calibration tree, DAQ information, trigger information
    Make a File "outAll.root",  with tree "joinAll", index of tree with name "run"
    //
    // Input tree configuration string:
    //
    const char *inputTrees="1#CPass1#run#tpcQA#TPCCPass1.root+1#VPass1#run#tpcQA#TPCVPass1.root+1#Pass1#run#tpcQA#TPCPass1.root+0#DAQ#run#joinTree#/home/miranov/test/dbQueries/fproductionJoin.root+0#C#run#dcs#OCDBscan.root+0#CE#run#Fits#CEtrend.root"
    Describe 6 trees to be merged (string separated be +):
      TObjArray *arrayInput = TString(inputTrees).Tokenize("+");
      TObjString = 1#CPass1#run#tpcQA#TPCCPass1.root
      TObjString = 1#VPass1#run#tpcQA#TPCVPass1.root
      TObjString = 1#Pass1#run#tpcQA#TPCPass1.root
      TObjString = 0#DAQ#run#joinTree#/home/miranov/test/dbQueries/fproductionJoin.root
      TObjString = 0#C#run#dcs#OCDBscan.root
      TObjString = 0#CE#run#Fits#CEtrend.root
    //
    Each tree is characterize by 5 parameters - separate by #
       description="1#CPass1#run#tpcQA#TPCCPass1.root"
       TString(description)->Tokenize("#").Print()
       Collection name='TObjArray', class='TObjArray', size=16
       TObjString = 1                    ==> (0/1) index is used
       TObjString = CPass1               ==> name of output branch  in output tree
       TObjString = run                  ==> name of the index
       TObjString = tpcQA                ==> name of the input tree in the input file
       TObjString = TPCCPass1.root       ==> name of the input file

 cache the list of file locally, cache valeus are stored in the location
 specified by optional argumen prefix
 2 new files are created
       <fileIn>.cache    - file with the location of cahe files
       <fileIn>.cacheLog - log file +list of files which can not be cached


    fileIn = "TPCCPass1.list";
    cachePrefix = "";

 join trees from the list  and make a common tree - stored in the file


    Example:
    const char * fout="TPCCpass1.root";
    const char *treeOut="tpcQA"
    const char *treeIn="tpcQA"
    const char * flist="TPCCPass1.list"
