/// \ingroup management
/// \class AliMpSegmentation
/// \brief Singleton container class for mapping segmentations
///
/// It provides access to mapping segmentations based on the
/// AliMpVSegmentation interface and to segmentations underlying
/// detectors (sector, slat, trigger).                                  \n
/// Mapping segmentations for all detection elements
/// are created at the first call to AliMpSegmentation::Instance().
/// The class is a singleton, it has all constructors
/// private, except for the special constructor for Root I/O.
