def move(selection, vector, copy=False, subelements=False):
"""move(selection, vector, [copy], [subelements])
Moves or copies selected objects.
Parameters
----------
selection: single object / list of objects / selection set
When dealing with nested objects, use `Gui.Selection.getSelectionEx("", 0)`
to create the selection set.
vector: App.Vector
Delta vector.
copy: bool, optional
Defaults to `False`.
If `True` the selected objects are not moved, but moved copies are
created instead.
subelements: bool, optional
Defaults to `False`.
If `True` subelements instead of whole objects are processed.
Only used if selection is a selection set.
Returns
-------
single object / list with 2 or more objects / empty list
The objects (or their copies)
