Keep explicitly the number of primary vertices in the output #14

vertex_isValid().size() should already do the job, @blinkseb can you confirm ?

vertex_isValid().size() returns the number of primary vertices, not the number of valid primary vertices. If you want the number of valid vertices, you have to iterate over the isValid array, which IIRC is a vector of bool.

which is, as far as I know, to study PU dependence, so it should be doing the job
