* Factory class registered in ServiceProvider to create a ViewHelperResolver.

* Note fluid is a failsafe mode aware extensions since its used in the install
* tool. We thus need a ServiceProvider.php to correctly instantiate / inject
* these class objects. This would be simple, but ViewHelperResolver has state,
* and the failsafe mode expects injected services to not have state.
*
* So, to retrieve a ViewHelperResolver instance, an instance of this factory
* is retrieved instead (which is a singleton), which then creates a 'fresh'
* instance of the ViewHelperResolver each time create() is called.
*
* @internal May change / vanish any time
