Implement kinematics computation for track points in SimModel

- Added computeTrackKinematics function to calculate velocity and acceleration for each point in a track using central differences.
- Introduced KinematicPoint and TrackKinematics types to represent computed kinematic data.
- Updated SimModel to include a derived property for track kinematics, automatically computing velocities and accelerations from position data.

This enhancement improves the analysis capabilities of track data within the simulation model.
