interceptors

[pete911]

would you be interested in adding interceptors? We already have the code that extends current router, so can create pull request. The idea is to add vargs interceptor to existing methods:

router.Get("/path", someHandler, interceptor1, interceptor2)
// method signature
router.Get(path string, handler http.HandlerFunc, interceptors... Intercetpr)
router.Post(...)
...

interceptors are varagrs, so it wouldn't break existing code

I thought that it would be just easier to create pull request to illustrate this - #68

Good idea @pete911, looking at it.
