Rather than add support to the various readers, it would be easier to
create a new file for animation.  Somebody else had ideas on how to
improve the datafile support.  But a simple option would be to do the
following:

       (1) Add an 'INCLUDE' keyword to the VTK data file format.  This
       would be really useful.  Quite often one has a fixed grid and
       varying data.  One could put all the grid info in one file
       'INCLUDE' it where reqd.  It would also save a lot of space.

       (2) create a special "animation" VTK file that has a tag
       indicating time with a corresponding include for the data.
       This way one could create a file that has all the time related
       information without the readers being aware of the time.  OTOH
       handling all data in the same file should be fairly straight
       forward.

Does this make sense at all?
