Initial pass at new style Users Controller 

Initial Controller routes and methods:

- [x] get all users
- [x] get single user
- [x] get me
- [x] create user
- [x] update user
- [x] delete user

Test coverage routes and methods:

- [ ] get all users
- [ ] get single user
- [ ] get current user
- [ ] create user
- [ ] update user
- [x] delete user
Rather than creating a one-off method, what if you could register a route to a callback and always specify an argument?
