       a unique token

	 my $e = $form->element( { type => 'Token' } );

	 my $p = $form->element( { plugin => 'Token' } );

DESCRIPTION
       This field can prevent CSRF attacks. It contains a random token. After
       submission the token is checked with the token which is stored in the

       Catalyst::Controller::HTML::FormFu for a convenient way how to use it.

   session_key
       Session key which is used to store the tokens. Defaults to "__token".

       HTML::FormFu::Constraint::Required.

   message
       Set the error message.

METHODS
   expire_token
       This method looks in the session for expired tokens and removes them.

   get_token
       Generates a new token and stores it in the stash.

       exists, 0 otherwise.
