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.....)                                     
                                                                      

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

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

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

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