Detailed Description

Module for fitting a vertex using the Geometric3DVertexFitter.

It selects primary PFParticles, and then collects all tracks associated to its daughters; if at least 2 tracks are found, they are passed to the vertex fitter.

Inputs are: a PFParticle collection, and the associated tracks.

Outputs are: vector of recob::Vertex, Assns of (neutrino) recob::PFParticle to recob::Vertex, Assns of recob::Vertex and recob::Track with recob::VertexAssnMeta.

For configuration options see Geometric3DVertexFitter::Parameters
