    # Resets the router to use the stacks namespaced router.
    # This allows a router to mixin a module, and have that module
    # mixed in to child stacks/routers.  Effectively, this will reset the scope of inheritance so that a stack type can have particular route helpers
    #
    # When the router is rest, any routes declared in parent stacks will be lost.
    # @example
    #   MyStack.reset_router! # => Replaces the current router with MyStack::Router (instance)
    #
    # @api public
    def self.reset_router!
