Class Description

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

*-*-*-*-*-*Default constructor for Ntuple*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*        ==============================
TNtupleD(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.
*-*-*-*-*-*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.
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 Double_t *x)
*-*-*-*-*-*-*-*-*Fill a Ntuple with an array of floats*-*-*-*-*-*-*-*-*-*
*-*              =====================================
Int_t Fill(Double_t x0,Double_t x1,Double_t x2,Double_t x3,Double_t x4 ,Double_t x5,Double_t x6,Double_t x7,Double_t x8,Double_t x9 ,Double_t x10,Double_t x11,Double_t x12,Double_t x13,Double_t x14)
*-*-*-*-*-*-*-*-*Fill a Ntuple: Each Ntuple item is an argument*-*-*-*-*-*-*
*-*              ==============================================
Long64_t ReadFile(const char *filename, const char * /*branchDescriptor*/)
 read from filename as many columns as variables in the ntuple
 the function returns the number of rows found in the file
 The second argument "branchDescriptor" is currently not used.
 Lines in the input file starting with "#" are ignored.
void Streamer(TBuffer &b)
*-*-*-*-*-*-*-*-*Stream a class object*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*              =========================================
TNtupleD(const TNtupleD&)
TNtupleD& operator=(const TNtupleD&)
Int_t GetNvar()
{ return fNvar; }
Double_t * GetArgs()
{ return fArgs; }
