abstract class ControllerBase

Utility base class for thin controllers.

Controllers that use this base class have access to a number of utility methods and to the Container, which can greatly reduce boilerplate dependency handling code. However, it also makes the class considerably more difficult to unit test. Therefore this base class should only be used by controller classes that contain only trivial glue code. Controllers that contain sufficiently complex logic that it's worth testing should not use this base class but use ContainerInjectionInterface instead, or even better be refactored to be trivial glue code.

The services exposed here are those that it is reasonable for a well-behaved controller to leverage. A controller that needs other services may need to be refactored into a thin controller and a dependent unit-testable service.
