//   AliAnalysysDataContainer - Container of data of arbitrary type deriving
//      from TObject used for analysis. A container must be connected to the 
//      output data slot of a single analysis task (producer) , but also as 
//      input slot for possibly several other tasks (consumers). The connected 
//      slots must enforce the same data type as the container (or a derived type).
//      A container becomes the owner of the contained data once this was produced.
//
// Containers should be defined by the analysis module using:
//
//   AliAnalysisModule::AddContainer(const char *name, TClass *type);
//
// A container should be connected to a producer:

//   AliAnalysisModule::ConnectOutput(AliAnalysisTask *task,
//                                    AliAnalysisDataContainer *cont)
// and to its consumers:
//
//   AliAnalysisModule::ConnectInput(AliAnalysisTask *task, Int_t islot,
//                                   AliAnalysisDataContainer *cont)
//
// The container will create an implicit connection between the producer task 
// and all consumers, which will become sub-tasks of the producer.
