vtk-m to Viskores

[wfullmer]

I see that vtk-m development has ended at 2.3 and the project has been archived and migrated to a new Viskores repo (https://github.com/Viskores/viskores). Are there plans for ascent to use Viskores in the future?

@wfullmer Yes, we will release Ascent 0.9.4 with VTK-m 2.3, and then we will move to use Viskores after that.
VTK-m 2.3 is equivalent to the first Viskores release.
