VTK-m now offers a more GPU aware set of defaults for kernel scheduling.
When VTK-m first launches a kernel we do system introspection and determine
what GPU's are on the machine and than match this information to a preset
table of values. The implementation is designed in a way that allows for
VTK-m to offer both specific presets for a given GPU ( V100 ) or for
an entire generation of cards ( Pascal ).

Currently VTK-m offers preset tables for the following GPU's:
- Tesla V100
- Tesla P100

If the hardware doesn't match a specific GPU card we than try to find the
nearest know hardware generation and use those defaults. Currently we offer
defaults for
- Older than Pascal Hardware
- Pascal Hardware
- Volta+ Hardware

Some users have workloads that don't align with the defaults provided by
VTK-m. When that is the cause, it is possible to override the defaults
by binding a custom function to `vtkm::cont::cuda::InitScheduleParameters`.
As shown below:

```cpp
  ScheduleParameters CustomScheduleValues(char const* name,
                                          int major,
                                          int minor,
                                          int multiProcessorCount,
                                          int maxThreadsPerMultiProcessor,
                                          int maxThreadsPerBlock)
  {

    ScheduleParameters params  {
        64 * multiProcessorCount,  //1d blocks
        64,                        //1d threads per block
        64 * multiProcessorCount,  //2d blocks
        { 8, 8, 1 },               //2d threads per block
        64 * multiProcessorCount,  //3d blocks
        { 4, 4, 4 } };             //3d threads per block
    return params;
  }
  vtkm::cont::cuda::InitScheduleParameters(&CustomScheduleValues);
```

These provide an appropriate BitPortal for use in worklets.

BitFields are:
- Stored in memory using a contiguous buffer of bits.
- Accessible via portals, a la ArrayHandle.
- Portals operate on individual bits or words.
- Operations may be atomic for safe use from concurrent kernels.

The new BitFieldToUnorderedSet device algorithm produces an ArrayHandle
containing the indices of all set bits, in no particular order.

The new AtomicInterface classes provide an abstraction into bitwise
atomic operations across control and execution environments and are used
to implement the BitPortals.

When reducing an input type that differs from the output type
you need to write a custom binary operator that also implements
how to do the unary transformation.

The default vtk-m device is an outdated concept and this is the
first step of removing it from VTK-m.

The last place remaining where it is being used is DynamicCellSet, which can
instead use `vtkm::cont::CellSet` as it itself is polymorphic.

In Make3DExplicitDataSetZoo, only 25 cells are added, but the variable `nCells`
is set to 27.

After the change to `ArrayHandleVirtual` where it became a subclass of
`vtkm::cont::ArrayHandle`, a few extra changes are required.

1. Functions with `ArrayHandleVirtual` as parameters will not be callable
with the superclass `ArrayHandle`. This is fixed by changing the argument
types to the superclass.
2. Add Serialization classes specializations for the superclass, as "is-a"
relation is not considered for class template parameters.
