[vtkusers] Reading independent Data into VTK

Hi Ryan,

It is most certainly possible to read such files into VTK (esp. if your
matlab files are hdf5 based), but it will most certainly not be
frustration free, with the said frustration coming from the incomplete
documentation/examples/etc. If you are a novice then do get yourself
prepared for quite some learning curve - or paying quite some consulting.
