base\Module createController()

Creates a controller instance based on the given route.

The route should be relative to this module. The method implements the following algorithm to resolve the given route:

1. If the route is empty, use $defaultRoute;
2. If the first segment of the route is a valid module ID as declared in $modules, call the module's createController() with the rest part of the route;
3. If the first segment of the route is found in $controllerMap, create a controller based on the corresponding configuration found in $controllerMap;
4. The given route is in the format of abc/def/xyz. Try either abc\DefController or abc\def\XyzController class within the controller namespace.

If any of the above steps resolves into a controller, it is returned together with the rest part of the route which will be treated as the action ID. Otherwise, false will be returned.
