This merge request is Phase 1 of several to implement the distributed parallel
contour tree in VTKm. This merge requests adds the base outline for the
algorithm. The implementation of the details of the algorithm in the
BoundaryRestrictedAugmentedContourTree.h is currently still missing.
However, these will require a substantial (~3000) lines of additional code.
The goal is to stage the integration process across merge requests to make
the review process simpler.

Because ArrayHandle currently only supports one device at a time, it is
possible that a `PrepareForInput` might actually need to wait for write
access so that it could move the data between devices. However, we don't
want the `Token` to be attached for writing because that could block
other read operations.
To get around this, add a hack to WaitToWrite to allow it to attach for
reading instead of writing.
An issue that was identified for the thread safety of `ArrayHandle` is
that if several threads are waiting to use an `ArrayHandle`, there might
be an expectation of the order in which the operations happen. For
example, if one thread is modifying the contents of an `ArrayHandle` and
another is reading those results, we would need the first one to start
before the second one.
To solve this, a queue is added to `ArrayHandle` such that when waiting
to read or write an `ArrayHandle` the `Token` has to be at the top of
the queue in addition to other requirements being met.
Additionally, an `Enqueue` method is added to add a `Token` to the queue
without blocking. This allows a control thread to queue the access and
then spawn a thread where the actual work will be done. As long as
everything is enqueued on the main thread, the operations will happen in
the expected order.

Initially, the probe filter would simply not set a value if a sample was
outside the input `DataSet`. This is not great as the memory could be
left uninitalized and lead to unpredictable results. The testing
compared these invalid results to 0, which seemed to work but is
probably unstable.
This was partially fixed by a previous change that consolidated to
mapping of cell data with a general routine that permuted data. However,
the fix did not extend to point data in the input, and it was not
possible to specify a particular invalid value.
This change specifically updates the probe filter so that invalid values
are set to a user-specified value.
The `Tuple.h` file was updated with some comments that were not updated
in `Tuple.h.in`. This caused the pyexpander script to fail with
mismatched files.

This fixes a bug introduced in commit
93d87e06fd7a0ef479a324e5cd2453c1c7ece0ee
Part of the commit moved fromusing a `BoundaryState` object to keeping
boundary flags in a `vtkm::Vec<bool,3>`. However, the meaning of the
flag got inverted. The `BoundaryState::IsRadiusIn?Boundary` methods
returned true if the current location was inside the bounds (i.e. _not_
on the boundary), but the new flags are true if the current location is
on the boundary (the inverse).
The updating of the code for the `StructuredPointGradient::Jacobian`
method got the flag somewhat wrong and scaled the wrong case.

Selecting the pixel type just means that lodepng casts it to that type
for it then to be cast to the type VTK-m uses. Since VTK-m always uses
the same type, there is little value for changing the intermediate cast.
Updated the image writer classes to better follow VTK-m naming
convention (i.e. use `ImageWriterPNG` instead of `PNGWriter`). The
structure of the image writer class now also better matches the
interface for the VTK writer.
Also put the implementation of the image writers into the `vtkm_io`
library so that it only has to be compiled once.
Updated the image reader classes to better follow VTK-m naming
convention (i.e. use `ImageReaderPNG` instead of `PNGReader`).
