2. Methods can be no longer than five lines of code.
3. Pass no more than four parameters into a method. Hash options are parameters.
4. Controllers can instantiate only one object. Therefore, views can only know about one instance variable and views should only send messages to that object (@object.collaborator.value is not allowed).
