-// Analysis class for Underlying Event studies
-//
-// Look for correlations on the tranverse regions to
-// the leading charged jet
-//
-// This class needs as input AOD with track and Jets.
-// The output is a list of histograms
-//
-// AOD can be either connected to the InputEventHandler
-// for a chain of AOD files
-// or
-// to the OutputEventHandler
-// for a chain of ESD files, so this case class should be
-// in the train after the Jet finder
