Class Description

 A Branch for the case of an object                                   
                                                                      

*-*-*-*-*-*Default constructor for BranchElement*-*-*-*-*-*-*-*-*-*
*-*        ====================================

 Create a BranchElement

 If splitlevel > 0 this branch in turn is split into sub branches

 Create a BranchElement

 If splitlevel > 0 this branch in turn is split into sub branches

*-*-*-*-*-*Default destructor for a BranchElement*-*-*-*-*-*-*-*-*-*-*-*
*-*        =====================================

set branch/leaf name/title in case of a TClonesArray sub-branch

*-*-*-*-*-*-*-*Loop on all leaves of this branch to fill Basket buffer*-*-*
*-*            =======================================================

  Fill buffers of this branch

*-*-*-*-*Read all branches of a BranchElement and return total number of bytes
*-*      ====================================================================
   If entry = 0 take current entry number + 1
   If entry < 0 reset entry number to 0

  The function returns the number of bytes read from the input buffer.
  If entry does not exist or an I/O error occurs, the function returns 0.

  See IMPORTANT REMARKS in TTree::GetEntry

return pointer to TStreamerinfo object for the class of this branch
rebuild the info if not yet done

 Return maximum count value of the branchcount if any

 Get top level branch parent of this branch
 A top level branch has its fID negative.

 recursively find branch br in the list of branches of this branch.
 return null if br is not in this branch hierarchy.

 return type name of element in the branch

 Returns branch value. If the leaf is an array, j is the index in the array
 If leaf is an array inside a TClonesArray, len should be the length of the
 array.  If subarr is true, then len is actually the index within the sub-array

 Returns pointer to first data element of this branch
 Currently used only for members of type character

*-*-*-*-*Return TRUE if more than one leaf, FALSE otherwise*-*
*-*      ==================================================

*-*-*-*-*-*-*-*-*-*-*-*Print TBranch parameters*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*                    ========================

 Prints leaf value

 Read buffers for this branch

*-*-*-*-*-*-*-*Reset a Branch*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*            ====================

    Existing buffers are deleted
    Entries, max and min are reset

*-*-*-*-*-*-*-*Set address of this branch*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*            ====================

*-*-*-*-*-*-*-*Set the AutoDelete bit
*-*            ====================
  This function can be used to instruct Root in TBranchElement::ReadBasket
  to not delete the object referenced by a branchelement before reading a
  new entry. By default, the object is deleted.
  If autodel is kTRUE, this existing object will be deleted, a new object
    created by the default constructor, then object->Streamer called.
  If autodel is kFALSE, the existing object is not deleted. Root assumes
    that the user is taking care of deleting any internal object or array
    This can be done in Streamer itself.
  If this branch has sub-branches, the function sets autodel for these
  branches as well.
  We STRONGLY suggest to activate this option by default when you create
  the top level branch. This will make the read phase more efficient
  because it minimizes the numbers of new/delete operations.
  Once this option has been set and the Tree is written to a file, it is
  not necessary to specify the option again when reading, unless you
  want to set the opposite mode.

 Reset basket size for all subbranches of this branchelement

 Set the branch count for this branch

 unroll base classes and loop on all elements of class cl
