6// Class for handling of ESD track cuts
7//
8// TODO:
9// - add functionality to save and load cuts
10// - fix the n sigma cut so it is really a n sigma cut
11// - add different ways to make track to vertex cut
12// - add histograms for kinematic cut variables?
13// - upper and lower cuts for all (non-boolean) cuts
14// - update print method
15// - is there a smarter way to manage the cuts?
