Detailed Description

Stores a vector of information about the flavor history of partons as well as a classification of the event.

It will return the following: nb = number of genjets that are matched to b partons nc = number of genjets that are matched to c partons

This can be used to classify the event, for instance, as W+bb (2 b partons), W+c (1 c parton), etc.
