    # Public: Instantiate page classes and call instance methods to navigate browser through the site
    #
    # If page navigation is too complex to use routes, you can always instantiate page classes within this method
    # body.
    #
    # Example
    #
    # def traverse(opts = {})
    #   visit(LoginPage).login
    #   opts[:do] == 1 ? on(PageOne).method_one : on(PageOne).method_two
    #   on(PageTwo).do_things(opts)
    # end
    #
    # Returns nothing.
