Sandia National Laboratories recently changed management from the
Sandia Corporation to the National Technology & Engineering Solutions
of Sandia, LLC (NTESS). The copyright statements need to be updated
accordingly.
Added cont/testing/ExplicitTestData.h which includes several explicit datasets. These datasets come from VTK data generated in VisIt. The new unit tests build datasets in several different ways and do some basic validation.
Add some new methods for DataSetFieldAdd class to improve usability.
