		Returns true if the specified username and password correspond to a registered
		user.
	auth_redirect()
		If a user is not logged in, he or she will be redirected to WordPress' login page before

		Upon sucessfully logging in, the user is sent back to the page in question.
	wp_redirect($location)
		Redirects a browser to the absolute URI specified by the $location parameter.
	wp_setcookie($username, $password, $already_md5 = false, $home =
		'', $siteurl = '')
		Sets the WordPress cookies for a logged in user. See WordPress Cookies.
