Picky is an easy to use and fast Ruby semantic search engine that helps your users find what they are looking for.

Picky::Index#geo_categories

Geo search, searches in a rectangle (almost square) in the lat/long coordinate system.

Note: It uses #ranged_category.

Parameters:
* lat_name: The latitude's name as used in #category.
* lng_name: The longitude's name as used in #category.
* radius: The distance (in km) around the query point which we search for results.

Note: Picky uses a square, not a circle. That should be ok for most usages.

Options
* precision: Default 1 (20% error margin, very fast), up to 5 (5% error margin, slower) makes sense.
* lat_from: The data category to take the data for the latitude from.
* lng_from: The data category to take the data for the longitude from.

THINK Will have to write a wrapper that combines two categories that are
indexed simultaneously, since lat/lng are correlated.
