Some of the data sets that are included from VTK-m are derived from the VisIt Tutorial Data (https://www.visitusers.org/index.php?title=Tutorial_Data). These are covered by the VisIt license, as communicated by Eric Brugger. Although the license for these data is compatible with VTK-m's license, we should still attribute the source of the data and make clear the copyrights. The data are moved into the third_party directory, and readmes are added to document everything. The noise.vtk and noise.bov files have been renamed example.vtk and example_temp.bov to match the name of the file in the VisIt tutorial data archive. The ucd3d.vtk file, which is similar to the curv3d.silo data but altered, has been removed. It was not used for any tests. It was referenced in a couple of example programs, but the reference is easily changed.
