Create a hook to extend Liferay and provide User's address validation

We need to develop this for Liferay 6.2 CE GA 1. Use this repository:
https://svn.rivetlogic.com/repos/rivets/logicstacks/hrportal/branches/6.2%20CE%20GA%201/

This should be a stand alone hook that uses a service developed by you. This service should validate address using google API:
https://developers.google.com/maps/documentation/geocoding/

When a user is created the hook will validate the provided User address and if it not valid will inform the user and provide options that are valid according to Google service.
