Development roadmap

Here is what I'm planning to do to contribute to this project:

#Larger radii It would be good to add functionality to allow more than 5 miles worth of postcode data to be available via the 'nearest' function of the API

1. This will mean that the API will only return postcode areas (e.g. AB1) that fall within the radius.
2. It may be best not to allow that data to be accessible via HTML until we have checked that all the links will work with postcode area requests.

#Sample data It would be helpful to add functionality to the rake task so that a small sample of the data can be made available so that developers don't have to wait several days whilst their development machine builds the database from the OS data.
