The DynamicCellSet class has been replaced with UnknownCellSet.
Likewise, the DynamicCellSetBase class (a templated version of
DynamicCellSet) has been replaced with UncertainCellSet.
These changes principally follow the changes to the UnknownArrayHandle
management class. The ArrayHandle version of a polymorphic manager has
gone through several refinements from DynamicArrayHandle to
VariantArrayHandle to its current form as UnknownArrayHandle.
Throughout these improvements for ArrayHandle, the equivalent classes for
CellSet have lagged behind. The CellSet version is decidedly simpler
because CellSet itself is polymorphic, but there were definitely
improvements to be had.
The biggest improvement was to remove the templating from the basic unknown
cell set. The old DynamicArrayHandle was actually a type alias for
DynamicArrayHandleBase<VTKM_DEFAULT_CELL_SET_LIST>. As
VTKM_DEFAULT_CELL_SET_LIST tends to be pretty long, DynamicArrayHandle
was actually a really long type. In contrast, UnknownArrayHandle is its
own untemplated class and will show up in linker symbols as such.
