PHP Route Controller: Register routes and dispatch controller requests

This class can register routes and dispatch controller requests.

It can register one or more request URL route patterns and assign closure functions to dispatch requests to those URLs.

It can also take an optional closure function to handle errors that happened during the dispatching of a request of a registered route.

The class can process the incoming HTTP request and check if it matches any of the registered routes, so it can dispatch the request to the respective closure function.
