#3362: Add function for DBSCAN clustering algorithm
-------------------------+---------------------------
 Reporter:  dbaston      |      Owner:  pramsey

Component:  postgis      |    Version:  trunk

-------------------------+---------------------------
 The DBSCAN clustering algorithm ([https://en.wikipedia.org/wiki/DBSCAN])
 seems to receive a good bit of attention in literature and practice;
 having a PostGIS implementation would be nice.

 The existing clustering functions are in fact a special case of DBSCAN,
 with minPoints = 1, so this addition would complement existing
 capabilities nicely.
