/**
* This class demonstrates the basic pattern for injecting a controller into
* other controllers:
* <p>
* 1. give the controller an interface that exposes the public methods of
* interest
* <p>
* 2. in the application's Guice module, bind the interface to the controller
* implementation
* <p>
* 3. inject the controller interface into other conrollers
* <p>
* Controllers that are to be injected into other controllers don't have to
* implement an interface, but this is a best practice, as it facilitates
* testing, and decouples objects.
