[WIP] Add type on annotation and handle it

PR for https://github.com/FriendsOfSymfony/FOSHttpCacheBundle/issues/160

I have to replace UrlGenerator with Router because I need to know if a route has parameters, and then replace all token with a wildcard.

I also change method scope to protected. It make possible to fit for special need.
why convert all methods to protected? this will make it hard to work on the code and keep BC.
