Compusure Drupal development

For quite a long time, Drupal has had several "friends APIs". Buddylist, Buddylist2, Friend, Ajax Friend, User Relationships, FriendList, etc.
This made it _really_ hard for module developers to just ask: "are user A and user B friends...?" Each module had a different way of answering that question, and with different outcomes.
This API is meant to be the answer to this problem.
It provides a general API which answers the most important questions about user relations. Who are user A's friends? Is user A friends with User B? What elation types are available?
Right now, the API interfaces with FriendList as a demonstration. However, it has a _simple_ plugin architecture, so that any API can be used.
