Detailed Description

Interface for updating Trk::PatternTrackParameters, the fast internal representation of track parameters in the (inner detector) pattern recognition tools, with a measurement.

The interface provides methods for adding or removing a measurement to/from a track state as well as calculating chi2 contributions. The methods are the same tasks as the standard Trk::IUpdator, but instead of the EDM Trk::TrackParameters it works with Trk::PatternTrackParameters. The interface is aimed at an implementation using the Kalman filter gain formalism.
