going through the output.

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.

When a new file is added to VTK-m, the copyright statement should go at
the top of the file. The copyright contains a date. What should that date
be? I usually set the date to the current year so older files will have
an older copyright whereas newer files will have a newer one. The check
copyright script needs to be flexible on the date.

There was an error in the script that was copied over from Dax. It was
checking for the year 2011, the start of the Dax project, and replacing
that in the text. VTK-m started in 2014, so the script really needs to
check for that year instead.
