Google Contacts API integration

See http://groups.drupal.org/node/9824 for more information or to ask questions about this proposal.

The Google Contacts API allows users to retrieve their email contacts from a gmail account without giving a gmail password to the requesting site. This system allows social networking site users to invite friends and find existing users they know without exposing their gmail accounts to malicious site owners or poor security practices. A Drupal module integrating with this API would allow site users to retrieve their Gmail contacts and find other users on the Drupal site registered using email addresses in their contacts.

The module should also expose an API allowing other modules to retrieve contacts in the same way. Adding support for this API to other applicable Drupal modules would be a second stage for the project. Prospective students should study some of the relevant Drupal modules (Invite, User Relationships, Private Messages, Buddylist, etc.) and present a list of the projects they would add support for the API to.

This project https://www.drupal.org/project/gmail_contact provides Integration to retrieve Gmail Contacts.
