/**
* Process the given URL, creating the appropriate controller and executing it.

* - instantiate the {@link Controller} object required by that rule, and call {@link Controller::setURLParams()} to give the URL paramters to the controller.
* - link the Controller's session to PHP's main session, using {@link Controller::setSession()}.
* - call {@link Controller::run()} on that controller
* - save the Controller's session back into PHP's main session.
* - output the response to the browser, using {@link HTTPResponse::output()}.
*
* @param $url String, the URL the user is visiting, without the querystring.
* @uses getControllerForURL() rule-lookup logic is handled by this.
* @uses Controller::run() Controller::run() handles the page logic for a Director::direct() call.
