Jobs fail when duplicated line is passed to the HltTisTos functor collection
If a line is duplicated in a list that is passed to the HltTisTos functor collection the job can fail. It is caused by this line in Rec. The map counts the duplicated line once, but n_valid_lines
counts it twice. It would be useful if a check could be added in the functor collection to check that no duplicated lines are passed.
