Detailed Description

A reconstructed Vertex providing position, error, chi2, ndof and reconstrudted tracks. The vertex can be valid, fake, or invalid. A valid vertex is one which has been obtained from a vertex fit of tracks, and all data is meaningful A fake vertex is a vertex which was not made out of a proper fit with tracks, but still has a position and error (chi2 and ndof are null). For a primary vertex, it could simply be the beam line. A fake vertex is considered valid. An invalid vertex has no meaningful data.
