/*
 * SAMPLE CODE AT BOTTOM!!!
 * 
 * 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.
