[Paraview] Input text

[Gerald Labedz]

Kevin and List, 
  Just a comment for the ParaView and vtk list: as a total newcomer to this
code but not to statistics or scientific visualization (though inactive for
a number of years), I'm pretty surprised that a simple ascii column (or
ordered n-tuple) reader was not put in here long ago! That threw me off, as
I just expected it to be available with zero effort. These days, it is
possible to do fairly sophisticated work even in what used to be junk tools.
For example, in Excel, generating tens of thousands of points, and needing
something much better than what Excel or similar programs provide for actual
analysis. It might be wise to expand the user community to those working in
such ways. I have a custom-written MPI beast of a simulator, yet, the
results are just ascii dumped as files, because to us, speed of construction
trumps all.
  thanks again for your help.
