Class Description

 A simple tree restricted to a list of float variables only.          
 Each variable goes to a separate branch.                             
  A Ntuple is created via                                             
  It is filled via:                                                   
     TNtuple::Fill(*x)  or                                            

TNtuple(): TTree()
*-*-*-*-*-*Default constructor for Ntuple*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*        ==============================

TNtuple(const char *name, const char *title, const char *varlist, Int_t bufsize) :TTree(name,title)
*-*-*-*-*-*-*-*-*-*-*-*-*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.

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

void Browse(TBrowser *b)

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(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*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*              =========================================
