    Fixed bug with complex geometries caused by to small buffer. Now it's possible to build
more complex geometries.Would be nice if somebody could check the way I handled it (buffer
reallocation).
    I also have some progress on integration with gis tools as shown here: http://bit.ly/1Rcvrjd

> Implement spatial query functionality in Drill to provide location based queries and
filtering. It could be similar to PostGIS for Postgres and allow queries like:
> select * from
>     (select columns[2] as location, columns[4] as lon, columns[3] as lat,
>         ST_DWithin(ST_Point(-121.895, 37.339), ST_Point(columns[4], columns[3]), 0.1)
as isWithin
>         from dfs.`default`.`/home/k255/drill/sample-data/CA-cities.csv`
>     )
>     where isWithin = true;
> Working proposal is available at http://github.com/k255 (see drill-gis and drill fork).
