Parameterized kalman
Implementation of the ParameterizedKalman is added. See for example https://indico.cern.ch/event/645022/#2-status-of-the-parametrized-k. An ExpertTracking option was added (ParameterizedKalman) that replaces the default Kalman with the parametrized version.
Update: Reorganized the code taking into account the different comments.
