The purpose of this plugin is to pass "status message" between screens through the following mechanisms: - Stores messages in the "$c->session" so that the application is free to redirect to the appropriate URL after an action is taken. - Associates a random 8-digit "token" with each messages, so it's completely unambiguous what message should be shown in each window/tab. - Only requires that the token (not the full message) be included in the redirect URL. - Automatically removes the message after the first time it is displayed. That way, if users hit refresh in their browsers they only see the messages the first time.
