// Modifications:
// Jeremy Meredith, Fri Feb 11 18:15:49 PST 2005
// Added HDF5 support to the existing HDF4 support.
//
// Jeremy Meredith, Fri Jul 15 15:27:49 PDT 2005
// Added fixes for multi-timestep Enzo runs.
//
// Jeremy Meredith, Wed Aug 3 10:21:56 PDT 2005
// Added support for 2D Enzo files.
//
// Jeremy Meredith, Thu Aug 11 14:35:39 PDT 2005
// Added new routine to unify global extents.
//
// Jeremy Meredith, Mon Apr 6 14:36:58 EDT 2009
// Added support for particle and grid file names.
// This is for support for the new "Packed AMR" format.
