Class Description

 A wrapper class supporting Hbook ntuples (CWN and RWN).              
 The normal TTree calls can be used, including TTree::Draw().         
 Data read directly from the Hbook file via THbookFile.               
 IMPORTANT NOTE                                                       
 When setting the branch address (via THbookTree::SetBranchAddress)   
 for a branch in an Hbook block containing several names, eg          
    Hbook block SELEVN with the following variables:                  
  *      1   * R*4  *         *              * SELEVN   * WGGS        
  *      2   * R*4  *         *              * SELEVN   * AM12        
  *      3   * R*4  *         *              * SELEVN   * AM34        
  *      4   * R*4  *         *              * SELEVN   * AM14        
  *      5   * R*4  *         *              * SELEVN   * AM32        
  *      6   * R*4  *         *              * SELEVN   * PtPI(4)     
  *      7   * R*4  *         *              * SELEVN   * PHIPI(4)    
  *      8   * R*4  *         *              * SELEVN   * THTPI(4)    
 one must define a C struct like:                                     
   struct {
