Method IsFirstReaderRank

IO/ParallelNetCDF/vtkPNetCDFPOPReader.cxx:710–719

------------------------------------------------------------------------------ Similar to above, but returns true only if the calling process is the first rank in the readerRanks vector. (This function exists because much of the file metadata is read by a single rank and broadcast to all the others.)
