  /** This class propagates {@link org.orekit.orbits.Orbit orbits} using
   * numerical integration.
   * <p>Numerical propagation is much more accurate than analytical propagation
   * like for example {@link org.orekit.propagation.analytical.KeplerianPropagator
   * Keplerian} or {@link org.orekit.propagation.analytical.EcksteinHechlerPropagator
   * Eckstein-Hechler}, but requires a few more steps to set up to be used properly.
   * Whereas analytical propagators are configured only thanks to their various
   * constructors and can be used immediately after construction, numerical propagators
   * configuration involve setting several parameters between construction time
   * and propagation time.</p>
   * <p>The configuration parameters that can be set are:</p>
   * <ul>
   *   <li>the initial spacecraft state ({@link #setInitialState(SpacecraftState)})</li>
   *   <li>the central attraction coefficient ({@link #setMu(double)})</li>
   *   <li>the various force models ({@link #addForceModel(ForceModel)},
   *   {@link #removeForceModels()})</li>
   *   <li>the {@link OrbitType type} of orbital parameters to be used for propagation
  *   ({@link #setOrbitType(OrbitType)}),</li>
  *   <li>the {@link PositionAngleType type} of position angle to be used in orbital parameters
  *   to be used for propagation where it is relevant ({@link
  *   #setPositionAngleType(PositionAngleType)}),</li>
  *   <li>whether {@link MatricesHarvester state transition matrices and Jacobians matrices}
  *   (with the option to include mass if a 7x7 initial matrix is passed) should be propagated along with orbital state
  *   ({@link #setupMatricesComputation(String, RealMatrix, DoubleArrayDictionary)}),</li>
  *   <li>whether {@link org.orekit.propagation.integration.AdditionalDerivativesProvider additional derivatives}
  *   should be propagated along with orbital state ({@link
  *   #addAdditionalDerivativesProvider(AdditionalDerivativesProvider)}),</li>
  *   <li>the discrete events that should be triggered during propagation
  *   ({@link #addEventDetector(EventDetector)},
  *   {@link #clearEventsDetectors()})</li>
  *   <li>the binding logic with the rest of the application ({@link #getMultiplexer()})</li>
  * </ul>
  * <p>From these configuration parameters, only the initial state is mandatory. The default
  * propagation settings are in {@link OrbitType#EQUINOCTIAL equinoctial} parameters with
  * {@link PositionAngleType#ECCENTRIC} longitude argument. If the central attraction coefficient
  * is not explicitly specified, the one used to define the initial orbit will be used.
  * However, specifying only the initial state and perhaps the central attraction coefficient
  * would mean the propagator would use only Keplerian forces. In this case, the simpler {@link
  * org.orekit.propagation.analytical.KeplerianPropagator KeplerianPropagator} class would
  * perhaps be more effective.</p>
  * <p>The underlying numerical integrator set up in the constructor may also have its own
  * configuration parameters. Typical configuration parameters for adaptive stepsize integrators
  * are the min, max and perhaps start step size as well as the absolute and/or relative errors
  * thresholds.</p>
  * <p>The state that is seen by the integrator is a simple seven elements double array.
  * The six first elements are either:
  * <ul>
  *   <li>the {@link org.orekit.orbits.EquinoctialOrbit equinoctial orbit parameters} (a, e<sub>x</sub>,
  *   e<sub>y</sub>, h<sub>x</sub>, h<sub>y</sub>, λ<sub>M</sub> or λ<sub>E</sub>
  *   or λ<sub>v</sub>) in meters and radians,</li>
  *   <li>the {@link org.orekit.orbits.KeplerianOrbit Keplerian orbit parameters} (a, e, i, ω, Ω,
  *   M or E or v) in meters and radians,</li>
  *   <li>the {@link org.orekit.orbits.CircularOrbit circular orbit parameters} (a, e<sub>x</sub>, e<sub>y</sub>, i,
  *   Ω, α<sub>M</sub> or α<sub>E</sub> or α<sub>v</sub>) in meters
  *   and radians,</li>
  *   <li>the {@link org.orekit.orbits.CartesianOrbit Cartesian orbit parameters} (x, y, z, v<sub>x</sub>,
  *   v<sub>y</sub>, v<sub>z</sub>) in meters and meters per seconds.
  * </ul>
  * <p> The last element is the mass in kilograms and changes only during thrusters firings
  *
  * <p>The following code snippet shows a typical setting for Low Earth Orbit propagation in
  * equinoctial parameters and true longitude argument:</p>
  * <pre>
  * final double dP       = 0.001;
  * final double minStep  = 0.001;
  * final double maxStep  = 500;
  * final double initStep = 60;
  * final double[][] tolerance = ToleranceProvider.getDefaultToleranceProvider(dP).getTolerances(orbit, OrbitType.EQUINOCTIAL);
  * AdaptiveStepsizeIntegrator integrator = new DormandPrince853Integrator(minStep, maxStep, tolerance[0], tolerance[1]);
  * integrator.setInitialStepSize(initStep);
  * propagator = new NumericalPropagator(integrator);
  * </pre>
  * <p>By default, at the end of the propagation, the propagator resets the initial state to the final state,
  * thus allowing a new propagation to be started from there without recomputing the part already performed.
  * This behaviour can be changed by calling {@link #setResetAtEnd(boolean)}.
  * </p>
  * <p>Beware the same instance cannot be used simultaneously by different threads, the class is <em>not</em>
  * thread-safe.</p>
