 Replying to [comment:2 neteler]:

 example (r62734) now generates a map.

 I've added a screenshot.

 AFAIU, e.g.

 - a point vector
 - a search radius has to be given
 - the module writes a raster map; the cell value of the raster map is the
 count how many points are within the search radius in this raster cell; in
 the screenshot yellow means count = 1, i.e. there is only 1 vector point
 within the search radius; red means count = 2, i.e. there are 2 vector
 points within the search radius.
