Build a structure for finding nearest neighbors.
Different implementations are used depending on what optional dependencies are available. The class NearestNeighborD uses CGAL in order to improve its functionality. It will fall back on less good code without it. The class NearestNeighborD uses ANN in order to improve its functionality. It will fall back on less good code without it.
