/*
 *
 * You need to put the name and values in quotes when you call the function, like this:
 * set_cookie( 'mycookie', 'visited 9 times', 30, '/', '', '' );. Don't forget to put in empty quotes for the unused parameters or
 * you'll get an error when you run the code. This makes the cookie named 'mycookie', with the value of 'visited 9 times', and with 
 * a life of 30 days, and the cookie is set to your root folder.
 *
 * The Set_Cookie values for 'domain' and 'secure' are not utilized. Use 'domain' on the Javascript cookie if you are using it on a 
 * subdomain, like widgets.yoursite.com, where the cookie is set on the widgets subdomain, but you need it to be accessible over the
 * whole yoursite.com domain.
 *
 * It's good practice to not assume the path to the site root will be set the way you want it by default, so do this manually as a 
 * rule, '/'. If no value is set for expires, it will only last as long as the current session of the visitor, and will be automatically 
 * deleted when they close their browser.
