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 {
    Float_t Wggs;
    Float_t Am12;
    Float_t Am34;
    Float_t Am14;
    Float_t Am32;
    Float_t Ptpi[4];
    Float_t Phipi[4];
    Float_t Thtpi[4];
 } event;
and set ONLY the first variable address with:
   h96->SetBranchAddress("Wggs",&event.Wggs);
