Detailed Description

Enhanced TList-derived class that implements correct merging for pt_hard binned production.

Must be activated using SetUseScaling(kTRUE). Otherwise the behavior is like a TList Scaling is recursively applied also to all nested lists deriving from TCollection fHistXsection and fHistTrials must be added directly to the list (not to a nested list)
