   * Function: main
   *
   * Purpose: h5diff main program
   *
   * Return: An  exit status of 0 means no differences were found, 1 means some
   *   differences were found.
   *
   * Programmer: Pedro Vicente, pvn@ncsa.uiuc.edu
   *
   * Date: May 9, 2003
   *
   * Comments:
   *
   * Modifications: July 2004
   *  Introduced the four modes:
   *   Normal mode: print the number of differences found and where they occured
   *   Report mode: print the above plus the differences
   *   Verbose mode: print the above plus a list of objects and warnings
   *   Quiet mode: do not print output
   *
   * November 2004: Leon Arber (larber@uiuc.edu)
   *     Additions that allow h5diff to be run in parallel
   *
   * February 2005: Leon Arber (larber@uiuc.edu)
   *   h5diff and ph5diff split into two files, one that is used
   *   to build a serial h5diff and one used to build a parallel h5diff
   *   Common functions have been moved to h5diff_common.c
   *
   * October 2005
   *  Introduced a new field 'not_cmp' to 'diff_opt_t' that detects
   *  if some objects are not comparable and prints the message
   *  "Some objects are not comparable"
   *
   * February 2007
   *  Added comparison for dataset regions.
   *  Added support for reading and comparing by hyperslabs for large files.
   *  Inclusion of a relative error formula to compare floating
   *   point numbers in order to deal with floating point uncertainty.
   *  Printing of dataset dimensions along with dataset name
   *
   *  November 19, 2007
   *    adopted the syntax h5diff  [OPTIONS]  file1 file2  [obj1[obj2]]
