71a2d3aa 20/// \class AliMUONSlatGeometryBuilder
21/// This Builder is designed according to the enveloppe methode. The basic idea is to be able to allow moves
22/// of the slats on the support panels.
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
30/// Reference system is the one described in the note ALICE-INT-2003-038 v.2 EDMS Id 406391
