 * This file contains defined constants that are used internally in the

 *
 * The first group of constants refer to netCDF variables, attributes, or 
 * dimensions in which the EXODUS II data are stored.  Using the defined 
 * constants will allow the names of the netCDF entities to be changed easily 
 * in the future if needed.  The first three letters of the constant identify 
 * the netCDF entity as a variable (VAR), dimension (DIM), or attribute (ATT).
 *
 * NOTE: The entity name should not have any blanks in it.  Blanks are
 *       technically legal but some netcdf utilities (ncgen in particular)
 *       fail when they encounter a blank in a name.
