``suffix``optional, string

• Copied objects are given new names.
• A ``suffix`` or ``prefix`` can be specified for objects to be copied.
  • If a ``suffix`` is specified then a ``prefix`` will be ignored
  • A leading dash is added to a ``suffix`` programmatically
  • A ``prefix`` is programmatically followed by a dash at the end
  • If ``suffix`` and ``prefix`` are empty, then a ``suffix``="-copy<integer>" is used if necessary, where _<integer>_ is the smallest natural number that ensures the uniqueness of the names of the copied objects.
