Kenneth Moreland 4650a1da96 Deprecate old methods from DynamicCellSet
The `DynamicCellSet` (and the related `DynamicCellSetBase`) are
deprecated and replaced with `UnknownCellSet` (and `UncertainCellSet`).
Thus, `UnknownCellSet` has some methods inherited from `DynamicCellSet`
but replaced with other functionality. These methods are now marked as
deprecated and their use is removed.
