You can create connection fields in any Connection, in case any ObjectType
that implements ``Node`` will have a default Connection.

The resolver of a connection field should return a list of objects of the
announced type. Those objects will automatically be wrapped in the edge and node
structure of the connection.

.. code:: python

class Faction(graphene.ObjectType):
name = graphene.String()
ships = relay.ConnectionField(ShipConnection)

def resolve_ships(self, info):
return []
# shall return a list of ship objects
return get_ship_list()
