T8b949e/**

* Radius-based Clustering algorithm:

* create a cluster using the first point from the cloned list.

* All points that are found within the neighborhood are added to this cluster.

* Then all the neighbors and the main point are removed from the list of points.

* It continues until the list is empty.

*

* Largely inspired from GridMarkerClusterer by M.Kergall
