This feature intends to add a spatial_stats metric aggregator designed for computing the most basic descriptive statistics for Exploratory Spatial Data Analysis. Much like the extended_stats aggregator for basic numerical analysis on non-spatial data sets, the spatial_stats aggregator will be specially designed for spatial data sets - specifically operating on geo_point fields. The aggregator will provide the following:
- Morans I - A measure of global spatial auto-correlation
- Geary's C - A measure of localized spatial auto-correlation (inversely related to Morans I)
- Getis-Ord - Hot spot analysis
- LISA - Indicators of local spatial association
