[vtkusers] Best Particle Based file format

[George Zagaris]

One possibility is to store the particles in a vtkUnstructuredGrid
where each cell is a VTK_VERTEX or you could have a single cell that
is of type VTK_POLY_VERTEX. Then, you can attach PointData (vectors or
scalars, etc.) as normal and read/write *.vtu files.

Best,
George
