* @class vtkSLACParticleReader
*
*
*
* A reader for a data format used by Omega3p, Tau3p, and several other tools
* used at the Standford Linear Accelerator Center (SLAC). The underlying
* format uses netCDF to store arrays, but also imposes some conventions
* to store a list of particles in 3D space.
*
* This reader supports pieces, but in actuality only loads anything in
* piece 0. All other pieces are empty.
