CellEvaluationDuplicate
• CellEvaluationDuplicate is an option for cells that determines if the front end should make a copy of the cell before performing an in-place evaluation of the cell.
• When a cell is evaluated in place, the result of the evaluation replaces the cell that was evaluated. By setting CellEvaluationDuplicate 
True, you can create a copy of the evaluated cell.
• New cells generated when CellEvaluationDuplicate is set to True have styles specified by the setting of DefaultDuplicateCellStyle for the notebook.
• CellEvaluationDuplicate is typically set for styles of cells rather than for individual cells.
• See also: CellEditDuplicate, Evaluatable, CellAutoOverwrite.
