  23 /// Those moves can be described with a simple set of parameters. The next step should be now to describe all
  24 /// the slats and their places by a unique
  25 /// class, which would make the SlatBuilder far more compact since now only three parameters can define a slat
  26 /// and its position, like:
  27 ///   - Bool_t rounded_shape_slat
  28 ///   - Float_t slat_length
  29 ///   - Float_t slat_number or Float_t slat_position
