As we discussed, the right thing to do is to swim the tracks (no problem) and their covariance (not coded yet) back to ~ the target (or a better approximation of where the vertex is) using the full b-field and then run vertexing.  The quick thing to do is to just ignore the varying b-field as we were before.
