"""
Spawns a new instance of the selected `collection` from the given `scene`.
If the `scene` is empty or null, the current active scene is used. Each spawned
instance has an empty owner object to control the instance as a whole (like Blender
uses it for collection instances).
@input Scene: Scene in which the collection belongs.
@input Collection: Collection to be spawned.
@input In: activates the node.
@input Transform: the transformation of the instance that should be
spawned. Please note that the collection's instance offset is
also taken into account.
@output Out: activated when a collection instance was spawned. It is
not activated when no collection is selected.
@output Top-Level Objects: all objects in the last spawned
collection that are direct children of the owner object of the
collection's instance.
@output All Objects: all objects in the last spawned collection.
@output Owner Object: The owning object of the last spawned
collection's instance.
