`UnknownCellSet` is an updated replacement for `DynamicCellSet`. The next step in the replacement is to change `DataSet` to use the new class. Also replaced `DynamicCellSet` with `UnknownCellSet` in a few places where `DynamicCellSet.h` was not directly included (and therefore now no longer included at all). This change would have to be made at some point anyway.
