One-to-many association descriptor.

One-to-many association defined on "one" side is always bi-directional relationship.

Method Summary
	`__init__(self, col)` Create descriptor for one-to-many associations.
	`addReferencedObjects(self, pairs)` Add referenced objects into database.
	`append(self, obj, value)` Append referenced object to association and integrate association data.
	`delReferencedObjects(self, pairs)` Delete referenced objects from database.
	`getAllKeys(self)` Return tuple of application object's and referenced object's primary key values.
	`reloadData(self, now)` Request reloading association relational data.
	`updateableAscData(self, obj, value)` Return pair of application object and referenced object.
	`updateReferencedObjects(self, pairs)` Update referenced objects in database.
Inherited from BiDirList
	`integrateRemove(self, obj, value)` Integrate association data when referenced object is removed from association.
	`integrateSave(self, obj, value)` Integrate association data when referenced object is appended to association.
	`remove(self, obj, value)` Remove referenced object from association and integrate association data.
Inherited from List
	`__get__(self, obj, cls)` Descriptor method to get iterator of referenced objects.
	`__set__(self, obj, value)` Assigning list of referenced objects is not implemented yet.
	`addAscData(self, pairs)` Add pair of application object's and referenced object's primary key values into database.
	`appendKey(self, okey, vkey)` Append referenced object relational data to association data.
	`contains(self, obj, value)` Check if object is referenced by application object.
	`delAscData(self, pairs)` Remove pair of application object's and referenced object's primary key values from database.
	`iterObjects(self, obj)` Return iterator of all referenced objects by application object.
	`justRemove(self, obj, value)` Remove referenced object from association.
	`len(self, obj)` Return amount of all referenced objects by application object.
	`loadData(self)` Load association data from database.
	`saveForeignKey(self, obj, vkey)` Save referenced object's primary key value.
	`update(self, obj)` Update in database relational data of association of given application object.
Inherited from AssociationReferenceProxy
	`save(self, obj, value)` Assign referenced object.
Inherited from object
	`__delattr__(...)` x.__delattr__('name') <==> del x.name
	`__getattribute__(...)` x.__getattribute__('name') <==> x.name
	`__hash__(x)` x.__hash__() <==> hash(x)
	`__reduce__(...)` helper for pickle
	`__reduce_ex__(...)` helper for pickle
	`__repr__(x)` x.__repr__() <==> repr(x)
	`__setattr__(...)` x.__setattr__('name', value) <==> x.name = value
	`__str__(x)` x.__str__() <==> str(x)
Inherited from type
	`__new__(T, S, ...)` T.__new__(S, ...) -> a new object with type S, a subtype of T

Instance Variable Summary
Inherited from List
	`appended`: Sets of referenced objects appended to association.
	`cache`: Association data cache - sets of referenced objects's primary key values per application object.
	`reload`: If true, then association data will be loaded from database.
	`removed`: Sets of referenced objects removed from association.
Inherited from AssociationReferenceProxy
	`association`: Referenced class' association object of bi-directional association.
	`broker`: Broker of application class.
	`col`: Application object's class attribute.
	`vbroker`: Broker of referenced application objects' class.
