This method checks if an object respects the arity from a category reverse
membership point of view and is in a valid workflow state.
For example we can check if every Order has at
most one Order Applied Rule in expected simulation_states.
Configuration example:
{ 'id' : 'applied_rule',
'description' : 'There must at most one Applied Rule using this order',
'type' : 'CategoryRelatedMembershipArityState',
'portal_type' : ('Applied Rule', ),
'base_category' : ('causality',)
