added JarriveFriendTableViewController as a tableview controller file with NSMutableArray: friends as only property so far
added a dummy friendUser class/(struct?) to populate _friend array. initWIthStyle now populates tableView _friends. initWithStyle should be called with argument UITableViewStylePlain-- the option we want( with no groups with headers and footers[i.e. in music app, songs, artists, albums, etc. are in a grouped style with groupings being alphabetical]).
moved count from numberOfSectionsInTableView to numberOfRowsInSection because it seems we only need one section. However, do not know how to reference sections. Will correct the method tomorrow. Finished more reading on UITableViews
