Implementing PseudoData smearing in one event loop in AnalysisTop
Previsouly, to use the Full (or all) JER model, one would need torun on MC, treating it as MC and then run second time onthe same MC but treating it as data. The changes are needed to allow to run both systematic models (MC and Pseudodata) in one event loop. This ameks the processing more convenient.
Currently works only for small R jets, but should not be hard to extend to large R jets.
Also sets the default JER smearing model to Full_PseudoData.
