4.3 Add a "Log Out" button to the welcome form that, when clicked, logs the user out by removing the

session variable. The user should be sent to the same page after clicking the button, which now

includes a login form.

4.4 Add an option to the login form that says "Remember me!" Save a cookie that identifies the user to

the server if the box is ticked and the login is successful. Even if the browser is closed, the user

should seem logged in on subsequent visits to the website.

NB: You can set the cookie's expiration time to anything sensible. Also, keep in mind that if the user

logs out manually by clicking the "Log Out" button, the cookie should be erased (set the expiration to a

date in the past).
