564ab75d2d Use _cdb_estimated_extent instead of ST_Extent 
With a 3.8M points table, this was a ~30% gain in my local env.

f7857945c1 Change feature density computation algorithm 
Now parameterize by the number of levels to traverse and
start with the level that covers the extent of the table
with at least N*N tiles (N=4).

554464e43e Use tile-recursive computation of feature density 
This is a more adaptive way of estimating the feature density to
determine the base Z level.
