Astaire is unable to route requests due to missing _routes method.

[postmodern]

I attempted to use Astaire edge with actionpack 3.0.0.rc.2, with the following hello world app:

require 'bundler'

Bundler.setup

require 'astaire'

class MyController < ActionController::Base

  include Astaire::DSL

  get '/hello' do
    render :text => 'Hello'
  end

end

run MyController

I received this exception when sending the app requests:

NameError: undefined local variable or method `_routes' for MyController:Class
