Static files OCaml example in readme

[gtach2o]

There are some typos in readme for OCaml static files example, but I was able to make it work like this:

let server_config: unit Naboris.ServerConfig.t = Naboris.ServerConfig.create ()
  |> Naboris.ServerConfig.setRequestHandler(fun route req res ->
    match ((Naboris.Route.meth route), (Naboris.Route.path route)) with
      | (Naboris.Method.GET, "static" :: static_path) ->
        Naboris.Res.static (Sys.getcwd() ^ "/static") static_path req res 
      | (Naboris.Method.GET, "/" :: []) ->
        Naboris.Res.static (Sys.getcwd() ^ "/static") ["/index.html"] req res
      | (Naboris.Method.GET, "" :: []) ->
        Naboris.Res.static (Sys.getcwd() ^ "/static") ["/index.html"] req res
      | _ ->
        res
          |> Naboris.Res.status 404
          |> Naboris.Res.text req "Resource not found.";
  )

let _ = Lwt_main.run begin
    Naboris.listenAndWaitForever 3000 server_config
end

By this index.html file from static folder is opened when gethttp://localhost:3000/ or http://localhost:3000.
Would be nice to have static folder by default or via parameter in ServerConfig for serving up static files. It can be useful for SPA.
