9// Analysis class for Underlying Event studies
10//
11// Look for correlations on the tranverse regions to
12// the leading charged jet
13//
14// This class needs as input AOD with track and Jets.
15// The output is a list of histograms
16//
17// AOD can be either connected to the InputEventHandler
18// for a chain of AOD files
19// or
20// to the OutputEventHandler
21// for a chain of ESD files, so this case class should be
22// in the train after the Jet finder
