Is your feature request related to a problem? Please describe.
We would like to determine DCA, PCA, etc of a track to the primary vertex, to decide what the DCA, PCA of that track is and decide on primary vs secondary tracks.
Describe the solution you'd like
Instead of having everyone (and their cat) develop a custom track projector or track propagator we should have an efficient service implementation that propagates to a surface and can be reused in algorithms.
Describe alternatives you've considered
Keep feeding through track propagator.
