ITrackExtrapolator interface does not provide propagation function without IGeometryInfo argument
Extrapolations done in PrKalmanFilter via TrackMasterExtrapolator do not need access to the geometry because scattering and energy loss is provided by parameterised scatters. The ITrackExtrapolator interface, however, currently forces us to always pass the geometry as argument, even if it's not used. This may be changed by adding a new propagate function to the interface and adapting the implementations accordingly.
Relevant implementations for PrKalmanFilter: Parabolic and Runge Kutta
