Errors with F.MIN, F.MAX, etc
When running the example script Moore/Hlt/Hlt2Conf/options/examples/b_to_open_charm/hlt2_b2oc_all_lines.py, I get a seg fault if I include ThOr functors such as F.MIN and F.MAX in a ParticleFilter. I'm currently doing this in the basic_builder.py (attached) function make_selected_ks().
