Detailed Description

Produces VertexAssociation and a ValueMap to the originating reco jets.

The PATVertexAssociationProducer produces a set of vertex associations for one or more collection of Candidates, and saves them in a ValueMap in the event.

These can be retrieved in PAT Layer 1 to be embedded in PAT Objects
