FEATURES TO ADD:

• fix edit links and iframe
• don't duplicate urls
• Make the preview or url show page contain the number of times someone has used that redirect.
• Allow the user creating the redirect to give a string to use as the shortened string. (localhost:3000/go/my_string redirects to my_url). Make sure to think about possible problems this could cause.
• Make everything gorgeous.

QUESTIONS:

• does preview variable have to be same as redirect variable since it is linking to that?
• http or https?
• why does iframe not work
• why does edit page not work
