[Paraview] Pointing paraview to read part of DATASET from separate files

[Mattijs Janssens]

I don't think there currently is a way for legacy vtk format to have 
separate parts. You could define your own format and create your own 
reader (don't know how hard that is though) or maybe there is a built-in 
format that can do this (Ensight?)

As a quick fix you could write binary legacy vtk files. Are a lot 
smaller and read much faster.
