When I looked at how ITK does things, I saw that ITK's set of 
"SeriesFileNames" classes do not fit into a heirarchy.  The 
GDCMSeriesFileNames, ArchetypeSeriesFileNames, 
RegularExpressionSeriesFileNames, etc. are all derived directly from 
itk::Object, it seems that there should be a base class.

None of the ITK classes seems to have to feature I want most: to be able 
to generate a list of file names based on the "*?[][^]" set of 
wildcards. Regular expressions are a bit too advanced for most of my users.

Maybe I'm trying to bite off more than I can chew.  Instead of writing a 
set of file name generators, I could just add a method to vtkDirectory 
so that it will filter the list of files according to a wildcard string, 
something like vtkDirectory::SetWildcardString("*.png").
