###Node.js ####Cookies in Response Object - Middleware
Okay, this one is really simple, but could be useful if you are using Express or Connect in your Node apps and need to make use of cookies in your templates. Granted, you could pass the cookie values you need to the templates in your routes, but in some cases you will find yourself doing this repetitively. This simple middleware makes the cookie() method and cookies object from your Express/Connect app accessible from within your templates.
I will be the first to admit that it is bad practice for templates to be setting values, so the cookie() method is unnecessary. But, I threw it in there just for fun.
