 * \section introduction Introduction
 * 
 * This Gudhi component is a wrapper around 
 * <a target="_blank" href="http://doc.cgal.org/latest/Spatial_searching/index.html">CGAL dD spatial searching algorithms</a>.
 * It provides a simplified API to perform (approximate) neighbor searches. Contrary to CGAL default behavior, the tree
 * does not store the points themselves, but stores indices.
 *
 * For more details about the data structure or the algorithms, or for more advanced usages, reading 
 * <a target="_blank" href="http://doc.cgal.org/latest/Spatial_searching/index.html">CGAL documentation</a>
 * is highly recommended.
 * 
 * \section spatial_searching_examples Example
 * 
 * This example generates 500 random points, then performs all-near-neighbors searches, and queries for nearest and furthest neighbors using different methods.
 *
