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

TNtupleD()

*-*-*-*-*-*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.
*-*

~TNtupleD()

*-*-*-*-*-*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*-*-*-*-*-*-*
*-*              ==============================================

void Streamer(TBuffer &b)

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

TNtupleD(const TNtupleD& ntd)
