// .NAME vtkSLACParticleReader
//
// .SECTION Description
//
// 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.

// Description:
// Convenience function that checks the dimensions of a 2D netCDF array that
// is supposed to be a set of tuples. It makes sure that the number of
// dimensions is expected and that the number of components in each tuple
// agree with what is expected. It then returns the number of tuples. An
// error is emitted and 0 is returned if the checks fail.
