+ * A old implementation of the symmetry plane estimator taken from the old FIDENTS.

+ * and measure their quality. But some additional criteria are used as well.
+ * Also, the calculation of "votes" differs.
+ * This implementation has the following properties:
+ * <ul>
+ * <li>Fast. A bit faster than the new robust algorithms of {@link SymmetryEstimatorRobust}
+ * and much faster that the {@link SymmetryEstimatorRobustMesh}.</li>
+ * <li>Best candidate planes are chosen based on the similarity of Gauss curvatures
+ * on both sides of the plane, inverse direction of normal vectors,
+ * and the distance of plane from centroid.</li>
+ * <li>Because the space of candidate planes is roughly approximated (several true-false rules),
+ * the final symmetry plane is computed by averaging best candidates (candidates with the most votes).</li>
+ * <li>Best results are achieved with Uniform Grid sampling with 200-300 points and averaging turn on.</li>
+ * <li>Should return reasonable results also for incomplete faces (was not tested).</li>
+ * </ul>
