/*
 *  Dependency injection can help you reduce coupling and increase testability, making your applications more maintainable.  
 *
 *  DependencyResolver gives you the best of both worlds by mixing a registry with call time dependency resolution. In addition, it provides significant resource
 *  usage advantages over other patterns, such as an object pool, because dependencies are only resolved when they are actually needed. 
 *
 *  It supports both constructor injection for class wide dependencies, as well as method injection for method specific dependencies.
