/// \class AliMpSlatSegmentation
/// \brief Implementation of AliMpVSegmentation for St345 slats.
/// 
/// Note that integer indices start at (0,0) on the bottom-left of the slat,
/// while floating point positions are relative to the center of the slat
/// (where the slat is to be understood as N PCBs of fixed size = 40cm
/// even if not all pads of a given PCBs are actually physically there).
