+//   AliTrigEvent - Base class for generic information exchanged by a trigger
+//                  device. Trigger inputs and outputs are represented and
+//                  handled via AliTrigEvent objects. Trigger events are typically
+//                  wrappers for the information exchanged on a single I/O slot
+//                  or a group of correlated inputs.
