/// \class AliMUONSegmentation
/// \brief Container class for modules segmentations
///
/// It provides access to segmentations on all levels:
/// - mapping segmentation
/// - DE segmentation (operating in local DE reference frame)
/// - module segmentation (operating in global reference frame)
///
/// As some detection elements are sharing the same objects
/// (AliMpVSegmentation, AliMUONVGeometryDESegmentation),
/// all segmentations objects have to be always deleted
/// altogether via deleting this container object.
