// Attaches COT hits to silicon-only tracks (IO = inside-out), and performs
// a combined fit to the COT and silicon hits. Currently, requires the 
// silicon-only tracks to have a TrackingAlgorithm = KalSvxStandAloneAlg.
//
// Alternatively, the module can be directed to attach COT hits to all
// tracks within a specified CdfTrackColl that do not already have COT 
// hits on them, irrespective of silicon hit content. A track with no
// hits of any kind is acceptable. The final fit will include all hits
// in the final track.
