"""Unassigns a related_object from its nest
A related_object (i.e. a smaller part of a whole) may be aggregated into zero
or one larger space or task. This function will remove that
aggregation relationship.
As all physical IFC model elements must be part of a hierarchical tree
called the "spatial decomposition", using this function will remove the
related_object from that tree. This is a dangerous operation and may result in
the related_object no longer being visible in IFC applications.
If the related_object is not part of an aggregation relationship, nothing will
happen.
