Description
The default ModifiableDataset copy constructor does not copy the values, leading to potential problems when two datasets reference the same values. A factory method for the conversion Dataset -> ModifiableDataset (with value cloning) would be a better option.
Additionally, it would be more efficient to be able to replace entire columns instead of individually changing variable values per row.
