Detect user login only with cookie. The best helper for cached WordPress sites.

== Description ==

This plugin sets user cookie when user is logged in.
You can use cookie as data store,
so you can use it as UI resource.

= Visibility =

This plugin adds class to `html` element.

- `ct-logged-in` The current user is logged in.
- `ct-not-logged-in` The current user is anonymous.

You can control elements visibility with CSS.

<pre>.some-element{
  display: none;
}
.ct-logged-in .some-element{
  display: block;
}</pre>

= From JavaScript =

You can use Global Object `CookieTasting` for utility.

- `CookieTasting.userName()` Returns user name. If not logged in, returns 'Guest'.
- `CookieTasting.lastUpdated()` Returns timestamp of last log in check. If this equals 0, it means that user is anonymous.

Besides that, this plugin checks periodically log-in status.
You can handle it with jQuery.

<pre>jQuery( document ).on( 'cookie.tasting', function( event, response ) {
	if ( response.login ) {
	    // User is logged in.
	    // If you use React...
	    setAttributes({ name: CookieTasting.userName() })
	} else {
	    // User is not logged in.
	}
} );</pre>

If you use react or something, updated the status with `setState()`.
