6 // Class for handling of ESD track cuts
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?
16 // - put comment to each variable
17 // - implement destructor !!!
