Class Description

                                                                      
 TNtuple                                                              
                                                                      
 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(): 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.

~TNtuple()
*-*-*-*-*-*Default destructor for an Ntuple*-*-*-*-*-*-*-*-*-*-*-*
*-*        ================================

Int_t Fill(Float_t *x)
*-*-*-*-*-*-*-*-*Fill a Ntuple with an array of floats*-*-*-*-*-*-*-*-*-*
