[Paraview] Adding a Reader

[Dave Semeraro]

Hello again,

I was able to figure out how to create a new reader for paraview. The problem I
described in my previous message went away when I used the correct
vtkTypeMacro. I am able to use the new reader to get data into paraview and
do a few things with it.

One thing that does not seem to work is the ExtractGrid filter. When I try to
use this filter with my data the VOI min and max values are all large 
negative numbers. My reader creates a structured points data set. How does 
the ExtractGrid filter get
the data extents from the upstream data source in paraview? I have looked 
at other
reader code in paraview like the plot3d reader and there does not seem to 
be any
special magic that I can find.

Thanks,
Dave
