/// \brief  Basic Kalman filter track class, with measurements.

/// \author H. Greenlee
///
/// This class inherits the following attributes from KFitTrack.
///
/// 1. Surface.
/// 2. Track state vector.
/// 3. Track direction parameter.
/// 4. Track error matrix.
/// 5. Propagation distance.
/// 6. Fit chisquare.
/// 7. Fit status.
///
/// This class adds the following attributes of its own.
///
/// 8. A collection of measurements, in the form of a vector
///    of shared pointers to KHitBase.
