10// AliAnalysysDataContainer - Container of data of arbitrary type deriving
11// from TObject used for analysis. A container must be connected to the
12// output data slot of a single analysis task (producer) , but also as
13// input slot for possibly several other tasks (consumers). The connected
14// slots must enforce the same data type as the container (or a derived type).
15// A container becomes the owner of the contained data once this was produced.
