/** An especial "ellipsoid" in 2D computed as the uncertainty iso-surfaces of a
 * (range,bearing) variable.
  *  The parameter space of this ellipsoid comprises these variables (in this
 * order):
  *   - range: Distance from sensor to feature.
  *   - bearing: Angle from +X to the line that goes from the sensor towards the
 * feature.
  *
  *  This class expects you to provide a mean vector of length 2 and a 2x2
 * covariance matrix, set with \a setCovMatrixAndMean().
  *
  * Please read the documentation of
 * CGeneralizedEllipsoidTemplate::setQuantiles() for learning
  *  the mathematical details about setting the desired confidence interval.
