Detailed Description

Wrapper class to facilitate vertex production.

It stores the recob::Vertex being built and the references to the tracks being used in the vertex fit. Tracks are stored in a vector of std::reference_wrapper<const recob::Track>, so the wrapper does not own the pointer to the original track object.
