Detailed Description

Helpers to calculate corrected 4-vectors w.r.t to a given orign.

A list of functions are defined to calculate the Jet 4-vector w.r.t to a given origin (i.e vertex). The calculation is done from the the corrected constituents position (or from the cells inside the constituents, not implemented yet). The calculation is done at the constituent scale : it does not take the jet 4-vector into account and so does not depend on the calibration of the jet.
