  10 // This Builder is designed according to the enveloppe methode. The basic idea is to be able to allow moves
  11 // of the slats on the support panels.
  12 // Those moves can be described with a simple set of parameters. The next step should be now to describe all
  13 // the slats and their places by a unique
  14 // class, which would make the SlatBuilder far more compact since now only three parameters can define a slat
  15 // and its position, like:
  16 //   * Bool_t rounded_shape_slat
  17 //   * Float_t slat_length
  18 //   * Float_t slat_number or Float_t slat_position
