class TNtuple: public TTree

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.

      NOTE:
       -Use TTree to create branches with variables of different data types.
       -Use TTree when the number of branches is large (> 100).

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

 Create a clone of this tree and copy nentries.

 By default copy all entries.
 Note that only active branches are copied.
 The compression level of the cloned tree is set to the destination file's
 compression level.

 See TTree::CloneTree for more details.

 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

 Fill a Ntuple with an array of floats

 Fill a Ntuple: Each Ntuple item is an argument

 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.
