Listing friends

So far thanks to this chapter we already have lists of users and the functionality for our users to build relationships. Now we need to combine these to build a friends list for our users. This would either be a user viewing their own friends, or viewing the friends of another user.

Our friends

To view our own friends, we would visit http://oursite/relationships. This would call our relationship controller's default method, which needs to get our friends and display them on the page.
