    # 
    # Implements SmartyPants.postprocess, which
    # performs smartypants replacements on the HTML file,
    # once it has been fully rendered.
    #
    # To add SmartyPants postprocessing to your custom
    # renderers, just mixin the module `include SmartyPants`
    #
    # You can also use this as a standalone SmartyPants
    # implementation.
    #
    # Example:
    #
    #   # Mixin
    #   class CoolRenderer < HTML
    #     include SmartyPants
    #     # more code here
    #   end
    #
    #   # Standalone
    #   Redcarpet::Render::SmartyPants.postprocess("you're")
    #

      def self.render(text)
