Attached country codes tool to footer

I found this very useful site which gives information on how people from one country can place a call to numbers other than their own.I have added the site tool to the footer. Just click the footer and it will take you to a page which has two selection boxes where you have to choose the country from where you are dialing and the country to which you want to make a call.Then the webpage shows you as to how to dial the number.I hope people would find it useful.
