/**
* AnnotationClassLoader loads routing information from a PHP class and its methods.
*
* You need to define an implementation for the getRouteDefaults() method. Most of the
* time, this method should define some PHP callable to be called for the route
* (a controller in MVC speak).
*
* The @Route annotation can be set on the class (for global parameters),
* and on each method.
*
* The @Route annotation main value is the route path. The annotation also
* recognizes several parameters: requirements, options, defaults, schemes,
* methods, host, and name. The name parameter is mandatory.
* Here is an example of how you should be able to use it:
*
* /**
* * @Route("/Blog")
* * /
* class Blog
* {
* /**
* * @Route("/", name="blog_index")
* * /
* public function index()
* {
* }
*
* /**
* * @Route("/{id}", name="blog_post", requirements = {"id" = "\d+"})
* * /
* public function show()
* {
* }
* }
