1.1.6 (2016-12-08)
__Bugfixes__
* Fix divide by zero condition in "denominator" branch of `OBS_GetMeasure`
when passing in a polygon ([#233](https://github.com/CartoDB/observatory-extension/pull/233)).
__Improvements__
* Use `ST_Subdivide` to improve performance when functions are called on very
complex geometries (with many points) ([#232](https://github.com/CartoDB/observatory-extension/pull/232))
* Improve raster scoring to more heavily weight boundaries with nearer to
correct number of points, and penalize boundaries with lots of blank space
([#232](https://github.com/CartoDB/observatory-extension/pull/232))
* Remove some redundant area calculations in `OBS_GetMeasure`
([#232](https://github.com/CartoDB/observatory-extension/pull/232))
* Replace use of `format('%L', var)` with proper use of `EXECUTE` and `$1` etc.
variables ([#231](https://github.com/CartoDB/observatory-extension/pull/231))
* Add test point for Brazil
([#229](https://github.com/CartoDB/observatory-extension/pull/229))
* Improvements to performance tests
([#229](https://github.com/CartoDB/observatory-extension/pull/229))
- Support simple and complex geometries
- Handle all code branches
- Add ability to persist results to JSON for graph visualization later
