  18 // Class AliMUONSlatGeometryBuilder
  19 // -------------------------------
  20 // Abstract base class for geometry construction per chamber.
  21 //
  22
  23
  24
  25 // This Builder is designed according to the enveloppe methode. The basic idea is to be able to allow moves
  26 // of the slats on the support panels.
  27 // Those moves can be described with a simple set of parameters. The next step should be now to describe all
  28 // the slats and their places by a unique
  29 // class, which would make the SlatBuilder far more compact since now only three parameters can define a slat
  30 // and its position, like:
  31 //   * Bool_t rounded_shape_slat
  32 //   * Float_t slat_length
  33 //   * Float_t slat_number or Float_t slat_position
  34 // Reference system is the one described in the note ALICE-INT-2003-038  v.2  EDMS Id 406391
