Production with standard track coordiates

added UseRhoCorrection switch to decide which isolation variable to use for selection (true by default)
switch to Rapidity selector (SelectorRapRange) for pile-up density computation in FastJet to ensure backward compatibility
addressed N-subjettiness warnings in 2.2.1 version

Third production run for Pierre

Restructured data to consist of one list of medium-level tracks. Both
primary and secondary tracks have the same "track" and "vertex"
component. In the case of the primary tracks, the only meaningful
vertex parameter value is the mass, which consists of only the tracks
in the jet. Other vertex parameters for the primary are set to dummy
values.

Second production run for Pierre

Restructured data to consist of two lists of medium-level track
arrays, one for the primary vertex tracks, one for the secondary
vertex tracks.
