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