c10e6eaf 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:
2057e0cc 16// * Bool_t rounded_shape_slat
17// * Float_t slat_length
18// * Float_t slat_number or Float_t slat_position
