/**
 * @brief Check service class restrictions by account.
 *
 * If there are no service_classes defined, everything is allowed.
 * If $usage is supplied, we check against a maximum count and return true if
 * the current usage is less than the subscriber plan allows. Otherwise we
 * return boolean true or false if the property is allowed (or not) in this
 * subscriber plan. An unset property for this service plan means the property
 * is allowed, so it is only necessary to provide negative properties for each
 * plan, or what the subscriber is not allowed to do.
 *
 * Like service_class_allows() but queries directly by account rather than channel.
 *
 * @see service_class_allows() if you have a channel_id instead of an account_id
 * @see account_service_class_fetch()
 *
 * @param int $aid The account_id to check
 * @param string $property The service class property to check for
 * @param int|boolean $usage (optional) The value to check against
 * @return boolean
