The tags manager is a simple service that works as a repository for tags. You can simple set up a new one by
creating a class that implements the Codefog\TagsBundle\Manager\ManagerInterface.
If you would like to update every field that implements your manager, make sure that your class implements the
Codefog\TagsBundle\Manager\DcaAwareInterface interface. Once that's done the built-in event listener
will trigger the interface methods each time the data container is loaded.
