Clone() public method

Clones a Database Cursor
This method wraps the native ups_cursor_clone function.
Clones an existing Cursor. The new Cursor will point to exactly the same item as the old Cursor. If the old Cursor did not point to any item, so will the new Cursor. If the old Cursor is bound to a Transaction, then the new Cursor will also be bound to this Transaction.
