20// AliAnalysysManager - Manager analysis class. Allows creation of several
37153431 21// analysis tasks and data containers storing their input/output. Allows
d3106602 22// connecting/chaining tasks via shared data containers. Serializes the current
23// event for all tasks depending only on initial input data.
