count_neighbors

This function counts the number of neighboring points within a specified
radius for each point in a given set of coordinates using a C implementation.

A cross between a 2D density plot and a scatter plot,
implemented as a 'ggplot2' geom. Points in the scatter plot are
colored by the number of neighboring points. This is useful to
visualize the 2D-distribution of points in case of overplotting.
