Originally, only files in the base directory were put into lfs.
With this change, all files in any subdirectory are also put into
lfs.
Also adding the test files for temporal advection to the data directory.
This behaves just like `ScanExclusive`, but rather than returning the
total sum, it is appended to the end of the output array.
This is in preparation for the CellSetExplicit refactoring described in
issue #408.
The `MultiBlock` class has been renamed to `PartitionedDataSet`, and its API
has been refactored to refer to "partitions", rather than "blocks".
Additionally, the `AddBlocks` method has been changed to `AppendPartitions` to
more accurately reflect the operation performed. The associated
`AssignerMultiBlock` class has also been renamed to
`AssignerPartitionedDataSet`.
This change is motivated towards unifying VTK-m's data model with VTK. VTK has
started to move away from `vtkMultiBlockDataSet`, which is a hierarchical tree
of nested datasets, to `vtkPartitionedDataSet`, which is always a flat vector
of datasets used to assist geometry distribution in multi-process environments.
This simplifies traversal during processing and clarifies the intent of the
container: The component datasets are partitions for distribution, not
organizational groupings (e.g. materials).
Ref #405
One of the dashboard compilers was complaining about not being able to
resolve which overload to use for std::size_t. (Perhaps on CUDA
std::size_t is sometimes not an unsigned 64-bit integer.) Try to correct
this by adding a templated method that casts anything to vtkm::UInt64.
The functions GetHumanReadableSize and GetSizeString accepted a
vtkm::UInt64 as the size, which should hold pretty much any reasonable
memory size and is compatible with std::size_t. But it has a different
sign-ness as vtkm::Id. So if you are holding an array size with vtkm::Id
(which is common), you could get a compiler warning when using these
functions, which is annoying. So, for convenience add a second form of
these methods that takes a vtkm::Id and automatically converts.
By removing the ability to have multiple CellSets in a DataSet
we can simplify the following things:
- Cell Fields now don't require a CellSet name when being constructed
- Filters don't need to manage what the active cellset is

For polygon cell shapes (that are not triangles or quadrilaterals),
interpolations are done by finding the center point and creating a
triangle fan around that point. Previously, the gradient was computed in
the same way as interpolation: identifying the correct triangle and
computing the gradient for that triangle.
The problem with that approach is that makes the gradient discontinuous
at the boundaries of this implicit triangle fan. To make things worse,
this discontinuity happens right at each vertex where gradient
calculations happen frequently. This means that when you ask for the
gradient at the vertex, you might get wildly different answers based on
floating point imprecision.
Get around this problem by creating a small triangle around the point in
question, interpolating values to that triangle, and use that for the
gradient. This makes for a smoother gradient transition around these
internal boundaries.
Although convenient, one of the issues of creating data with
MakeTestDataSet is that it is hard to look at the data created. It is
often helpful to be able to bring in the data into something like
ParaView or VisIt to play with it. To enable that, write them all out as
part of UnitTestVTKDataSetWriter.

This is a work around while we wait on requiring CMake 3.15 for all
cuda builds. At that point we can replace this with setting
`requires_static_builds` as part of the EXPORT_PROPERTIES of the

Once #377 is implemented we won't need this, but for now we have to
use the serial connectivity tables while validating the OrientNormals
output. Ensure that the serial device can be used during the validation
stage.
