 A simple tree restricted to a list of float variables only.          
                                                                      
 Each variable goes to a separate branch.                             
                                                                      
  A Ntuple is created via                                             
     TNtuple(name,title,varlist,bufsize)                              
  It is filled via:                                                   
     TNtuple::Fill(*x)  or                                            
     TNtuple::Fill(v1,v2,v3.....)

TNtuple()

*-*-*-*-*-*Default constructor for Ntuple*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*        ==============================

TNtuple(const TNtuple& tnt)

copy constructor

TNtuple& operator=(const TNtuple& tnt)

assignement operator

TNtuple(const char *name, const char *title, const char *varlist, Int_t bufsize)

*-*-*-*-*-*-*-*-*-*-*-*-*Create an Ntuple*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*                      ================
       The parameter varlist describes the list of the ntuple variables
       separated by a colon:
         example:  "x:y:z:energy"
       For each variable in the list a separate branch is created.

       Use TTree to create branches with variables of different data types.
*-*

~TNtuple()

*-*-*-*-*-*Default destructor for an Ntuple*-*-*-*-*-*-*-*-*-*-*-*
*-*        ================================

void ResetBranchAddresses()

 Reset the branch addresses to the internal fArgs array. Use this
 method when the addresses were changed via calls to SetBranchAddress().

void Browse(TBrowser *b)

 Browse content of the ntuple

Int_t Fill()

*-*-*-*-*-*-*-*-*Fill a Ntuple with current values in fArgs*-*-*-*-*-*-*
*-*              ==========================================
 Note that this function is protected.
 Currently called only by TChain::Merge

Int_t Fill(const Float_t *x)

 Fill a Ntuple with an array of floats

Int_t Fill(Float_t x0,Float_t x1,Float_t x2,Float_t x3,Float_t x4 ,Float_t x5,Float_t x6,Float_t x7,Float_t x8,Float_t x9 ,Float_t x10,Float_t x11,Float_t x12,Float_t x13,Float_t x14)

 Fill a Ntuple: Each Ntuple item is an argument

void Streamer(TBuffer &b)

*-*-*-*-*-*-*-*-*Stream a class object*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*              =========================================

Int_t Fill()

Int_t Fill(const Float_t *x)

Int_t GetNvar()

Long64_t ReadFile(const char *filename, const char *branchDescriptor="")
