[Paraview] File Series Reader as a Plugin

[Sean Ziegeler]

Ken,
Yes, that's correct.  The "Meta" (.mha, .mhd) reader exists in ParaView 
(actually in VTK) and I want to load in a file series.  And that answers 
my question, i.e., ParaView will load files of the same extension using 
the new plugin reader instead of the original one.

The reason I asked was that I seem to recall earlier versions of 
ParaView always using the _first_ reader for a given file extension if 
the extension conflicted with another reader.  I assume that has been 
changed recently.  Anyway, thanks for the answer.  I didn't want to 
spend time on this if there was no hope of it working.
