[Paraview] File formats for particle visualization

[Zhanping Liu]

Yes, the VTK EnSight Reader does support particle files while I am not sure
if the term "particles" Alan mentioned is just the one supported by the VTK
EnSight Reader. There seem to be multiple definitions of "particles".  For
example, the one in 'measured particles' (supported by the VTK EnSight
Reader) might be different from that in 'particle tracing'.
