# A couple of typos in comment lines in the original were elided to make the diff a bit clearer.

I needed a tool to add latitude and longitude to seeds.rb in a Rails application.

geocoder.rb uses the Google geocode api. An apikey is required. For limited use it is free. The apikey should be protected from prying eyes. (encryption, .gitignore, ...)

Geocoder#geocode takes an address string in canonical form ( "#{number} #{street} #{city} #{state}" ) as input. It returns latitude and longitude as a hash: { lat: 30.0000, lng: -90.000 }

seed_geocoder.rb extracts the address string from seeds.rb, requests the geocode hash from the Geocoder obj and writes the newseeds.rb file. 

The newseeds file does need some minor additional work to make it a functional seeds.rb.
