Controller class Null safety

Base class for request handling objects.

A controller is a discrete processing unit for requests. These units are linked together to form a series of steps that fully handle a request.

Subclasses must implement handle to respond to, modify or forward requests. This class must be subclassed. Router and ResourceController are common subclasses.
