AliFMDRing This class contains all stuff needed to do with a ring. It's used by the AliFMDDetector objects to instantise inner and outer rings. The AliFMDRing objects are shared by the AliFMDDetector objects, and owned by the AliFMDv1 object.
AliFMD1, AliFMD2, and AliFMD3 These are specialisation of AliFMDDetector, that contains the particularities of each of the sub-detector system. It is envisioned that the classes should also define the support volumes and material for each of the detectors.
