A command for returning all objects created with a multi-part object (e.g. a carrier) would be great.
`objectParts object`
Retuns: An array of all objects that were created together with this object. [object] if it's a single-part object.
E.g. if you use `objectParts carrier_part1` it gives:
`carrier_part1, carrier_part2,..._carrier_partN`
