Create a route with respond($method, $route, $callback) or respond($route, $callback) where callback is function ($request, $response)

$request->
    header($key)                        //Gets a request header
    cookie($key)                        //Gets a cookie from the request

    params()                            //Return all parameters
    params($mask = null)                //Return all parameters that match the mask array - extract() friendly
    validate($param, $err_msg = null)   //Starts a validator chain
    method()                            //Gets the request method
    method($method)                     //Checks if the request method is $method, i.e. method('post') => true
    isSecure($required = false)         //https? Redirect if $required is true and the request is not secure
    id()                                //Gets a unique ID for the request
    ip()                                //Get the request IP
