adds methods to new friend_repo to get friends of user, save friends to db, get the friends games, and compare the friends games with the user games to see which games are in common. Things left to do - finish the code to assign the name of the player in the database along with the player_id_64 which is currently saving correctly. After the realname is in there, when the viewis rendered for filters, we can pull out friends of the player by name and pass it to the view. Next when the players are clicked and submitted, we can call user.friends and find the players name in there (if we look in the db without that, it could possibly locate another friend since names are not unique, though they should be almost unique when tied to one user). After we get the player ids we can call the compare friends games which right now, takes an array of arrays, but honestly, we don't need to differentiate the different users at that point, we just need one big array of all friends games and then use the intersection & operator to find the games in common. Once the games are found in common, it passes back the common games as an array to the controller. The controller will then use those as part of the filters. Any games rendered to the user after this will be games that the user shares with those selected friends. Maybe we want to include the names of the users selected on the final page but I don't think we should.
