[Grant new user role after 3 conditions are met](https://ecaguide.org/library/simple/grant_new_user_role_after_3_conditions_are_met) This model automatically adds or removes a role from a user, when this gets updated, depending upon 3 conditions that are stored with the user entity. Only if all 3 conditions are met, the role gets added. In all other cases, the role gets removed.
