/**
 * @class   vtkExodusIIReader
 * @brief   Read exodus 2 files .ex2
 *
 * vtkExodusIIReader is a unstructured grid source object that reads ExodusII
 * files.  Most of the meta data associated with the file is loaded when
 * UpdateInformation is called.  This includes information like Title, number
 * of blocks, number and names of arrays. This data can be retrieved from
 * methods in this reader. Separate arrays that are meant to be a single
 * vector, are combined internally for convenience.  To be combined, the array
 * names have to be identical except for a trailing X,Y and Z (or x,y,z).  By
 * default cell and point arrays are not loaded.  However, the user can flag
 * arrays to load with the methods "SetPointResultArrayStatus" and
 * "SetElementResultArrayStatus".  The reader DOES NOT respond to piece requests
 *
