* Marks classes able to provide CSRF protection
*
* You can generate a CSRF token by using the method generateCsrfToken(). To
* this method you should pass a value that is unique to the page that should
* be secured against CSRF attacks. This value doesn't necessarily have to be
* secret. Implementations of this interface are responsible for adding more
* secret information.
*
* If you want to secure a form submission against CSRF attacks, you could
* supply an "intention" string. This way you make sure that the form can only
* be submitted to pages that are designed to handle the form, that is, that use
* the same intention string to validate the CSRF token with isCsrfTokenValid().
