Geokit 1.4.0

Geokit makes it easy to build location-based apps. Geokit provides geocoding, location finders, and distance calculation in an easy-to-use API.
If you have any tables with latitude/longitude columns in your database, or if you every wanted to easily query for "all the stores within a 50 mile radius," then Geokit is for you.
Geokit consists of a Rails plugin (geokit-rails) and a Gem (geokit-gem). You will be able to use the gem separately. The plugin requires the gem.

Main features:
- Distance calculations between two points on the earth. Calculate the distance in miles or KM, with all the trigonometry abstracted away by Geokit.
- ActiveRecord distance-based finders. For example, you can find all the points in your database within a 50-mile radius.
- Geocoding from multiple providers. It currently supports Google, Yahoo, Geocoder.us, Genames, and Geocoder.ca geocoders, and it provides a uniform response structure from all of them. It also provides a fail-over mechanism, in case your input fails to geocode in one service.
- IP-based location lookup utilizing hostip.info. Provide an IP address, and get city name and latitude/longitude in return.
- A before_filter helper to geocode the users location based on IP address, and retain the location in a cookie.

Enhancements

- Added suggested_bounds (Geokit:Bounds) property to GeoLoc. (Google geocoder only)
- Added LatLng#reverse_geocode convenience method (thanks Tisho Georgiev for all three)
