def freeze

Freeze the namespaced routes and setup the regexp matchers so that there can be no thread safety issues at runtime. 
def freeze
  opts[:namespaced_routes].freeze.each do |k,v|
    v.freeze
    self::RodaRequest.named_route_regexp(k)

def inherited(subclass)

Copy the named routes into the subclass when inheriting.

def named_route(name, namespace=nil)

Return the named route with the given name. 
def named_route(name, namespace=nil)

end

def named_routes(namespace=nil)

The names for the currently stored named routes

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
