9// Analysis class for Underlying Event studies w.r.t. leading track
10//
11// Look for correlations on the tranverse regions w.r.t
12// the leading track in the event
13//
14// This class needs input AODs.
15// The output is a list of analysis-specific containers.
16//
17// The 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,
22// in this case the class should be in the train after the jet-finder
23//

25// Arian Abrahantes Quintana
