def freeze

Freeze the namespaced routes so that there can be no thread safety issues at runtime. 
def freeze

  super
end

def inherited(subclass)

Copy the named routes into the subclass when inheriting. 
def inherited(subclass)

end

def named_route(name, namespace=nil)

Return the named route with the given name. 
def named_route(name, namespace=nil)
  opts[:namespaced_routes][namespace][name]
end

def named_routes(namespace=nil)

The names for the currently stored named routes 
def named_routes(namespace=nil)
  routes = opts[:namespaced_routes][namespace]
  routes ? routes.keys : []
end

def route(name=nil, namespace=nil, &block)

call super.
store the route block. Otherwise, this is the main route, so
If the given route has a name, treat it as a named route and 
def route(name=nil, namespace=nil, &block)
  if name

    opts[:namespaced_routes][namespace][name] = block
    self::RodaRequest.clear_named_route_regexp!(namespace)
