      Store that saves its data in a cookie.

      __In order to keep multiple tabs/windows of an application in sync, this
      store has to periodically (every 500ms) check the cookie__ for changes as
      there are no events that notify of changes in cookies. The recommended
      alternative is `Stores.LocalStorage` that also persistently stores data but
      instead of cookies relies on the `localStorage` API and does not need to poll
      for external changes.

      By default the cookie store will use a session cookie that expires and is
      deleted when the browser is closed. The cookie expiration period can be
      configured via setting
      [`Stores.Cooke#cookieExpirationTime`](#SimpleAuth-Stores-Cookie-cookieExpirationTime)
      though. This can also be used to implement "remember me" functionality that
      will either store the session persistently or in a session cookie depending
      whether the user opted in or not:

      ```js
      // app/controllers/login.js
      export default Ember.Controller.extend({
        rememberMe: false,

        rememberMeChanged: function() {
          this.get('session.store').cookieExpirationTime = this.get('rememberMe') ? (14 * 24 * 60 * 60) : null;
        }.observes('rememberMe')
      });
      ```

      `'simple-auth-session-store:cookie'` in Ember's container._
