Implementation of Video Queue (show queue, add and remove entries)

I chose to create a resource under user to allow access to queues using routes that include the user ID.  But I also kept the my_queue route at root which is sent to the same controller.  The controller is tolerant of an omitted user_id and assumes it to mean the current logged in user.  Note that this complicated my test writing so I had to write extra tests for various cases of user_id supplied and omitted.

Yup - that was one of the things I commented on - by allowing for the additional route as shown in the solution, I complicated the code by having to cover both cases where user_id is given in the request and where it's omitted and expected to be current_user.
