[Paraview] paraview .vtk file format.

[Dominik Szczerba]

There is a config file but I never checked it for colors. Otherwise set
it back in GUI. The time series has to have 001 etc in the finename, but
of course you need suffix too. I dont remeber by heart but it was sth
like file001.vth file002.vtk etc. Then there will be slider in the
properties to chose time step. Not too convenient though.
cheers
