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.
Previously, all declared policies had to implement every tag required by
the policy, even if it was the same as the default. In addition to being
annoying, this makes us less forward compatible because if we add a new
item to the policy any unchanged policy would become incorrect.
This change moves the default policy declarations from the default
policy to PolicyBase. The default policy inherits all of them without
any change. Other policies need only override those that are different
than the default.
The TryExecute function was based off of the ResolveFieldTypeAnd*
classes made for filters. To reduce the amount of code duplication,
modify these two filter classes to use the more general TryExecute
functionality.
Certain algorithms like VertexClustering only work on certain cellset types.
It is pointless to generate the code paths for structured data cell sets,
when the algorithm can't operate on those dataset types.
The base classes for all the filters are named with 'Filter' at the end.
Generally the convention in VTK-m is to place the most general
descriptor (in this case Filter) first, which makes it easier to find
items in ordered lists.
This commit resolves issue #59.
