The rendering classes do not actually manage windows, and window was not
descriptive of what this class was doing. We decided that the class was
mostly analogous to what we call a "view" in ParaView.
For header files, this only adds the file to IDE file lists, which is
convenient but not critical. However, the test did find a ligit error in
the hello_world example where the TBB build was actually using the
serial device adapter.
Previously, DynamicArrayHandle and DynamicCellSet had slightly different
interfaces to their CastTo feature. It was a bit confusing and not all
that easy to use.
This change simplifies and unifies them by making each class have a single
CopyTo method that takes a reference to a cast object (an ArrayHandle or
CellSet, respectively) and fills that object with the data contained if
the cast is successfull. This interface gets around having to declare
strange types.
Each object also has a Cast method that has to have a template parameter
specified and returns a reference of that type (if possible).
In addition, the old behavior is preserved for DynamicArrayHandle (but
not DynamicCellSet). To avoid confusion, the name of that cast method is
CastToTypeStorage. However, the method was chaned to not take parameters
to make it consistent with the other Cast method.
Also, the IsType methods have been modified to reflect changes in
cast/copy. IsType now no longer takes arguments. However, an alternate
IsSameType does the same thing but does take an argument.
Previously each device adapter only had a unique string name. This was
not the best when it came to developing data structures to track the status
of a given device at runtime.
This adds in a unique numeric identifier to each device adapter. This will
allow classes to easily create bitmasks / lookup tables for the validity of
devices.
The RuntimeDeviceInformation class allows developers to check if a given
device is supported on a machine at runtime. This allows developers to properly
check for CUDA support before running any worklets.
When writing multiple backend code users of vtkm need to use the
DeviceAdapterTraits classes, so therefore we should move them to vtkm::cont
to signify this.
vtkm::Id is a signed integer whereas size_t used by standard C++
functions is unsigned. It doesn't matter, but compilers like to complain
about it. Make any such conversions explicit.
Improve CMake module
Some improvements to VTKmConfig.cmake and the device configuration scripts to better support CMake projects using VTK-m.

Scatter in worklets
Add the functionality to perform a scatter operation from input to output in a worklet invocation. This allows you to, for example, specify a variable amount of outputs generated for each input.

Array transforms can now be created with an inverse functor, allowing for
casts back into the native array type. As a result, array transforms with
both a functor and inverse functor defined can perform read and write
operations. As an example, ArrayHandleCast now supports this operation. The
original implementation of ArrayHandleCast (i.e. read only) has been renamed
'ArrayHandleCastForInput'.
The original isosurface code was not treating the origin and spacing of
the point coordinates correctly. Instead, it was ignoring the origin and
spacing and instead scaling all point coordinates to be in the unit cube
in world space (except there was also an off-by-one error in that). This
change recompensates by adjusting the origin and spacing to make the
correct position where the geometry was previously errantly placed.

This is needed as it allows the policies specified in the root of
vtk-m to propagate properly to the examples. When CMake
sees a cmake_minimum_required command it resets all policy flags.
There were a couple of files checked into the git repository with DOS
line endings. Most git implementations really expect there to be Unix
line endings and should do the appropriate conversions as necessary.
This commit should change the line endings to the appropriate Unix endings.
