 Looks like Mohit will be working on this as part of GSoc and strk will be
 mentoring? or did I misunderstand?

 Excerpt from google summer of code

 {{{
  The idea is to design and implement hierarchical clustering to the point
 data in Postgres database and integrate it in CartoDB such that beyond a
 lower zoom level the spatially nearer points merge into one another to
 form a single point. The leaf nodes will contain the original point data
 and the intermediate nodes will have the count of leaf nodes below that
 level. It will implement SP-GiST indexing on the underlying postGIS
 database.
