class AliAnalysisTaskLeadingTrackUE: public AliAnalysisTask


 Analysis class for Underlying Event studies w.r.t. leading track

 Look for correlations on the tranverse regions w.r.t
 the leading track in the event

 This class needs input AODs.
 The output is a list of analysis-specific containers.

 The AOD can be either connected to the InputEventHandler
 for a chain of AOD files
 or
 to the OutputEventHandler
 for a chain of ESD files,
 in this case the class should be in the train after the jet-finder
