Pedro Vicente Nunes 4cb6c01d7f [svn-r8904] Purpose:
h5diff and h5repack changes

Description:
h5diff
introduced the following four modes of output:
 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 (h5diff always returns an exit code of 1 when differences are found)

    h5repack
     added an extra parameter for SZIP filter (coding method)
     the new syntax is
     -f SZIP=<pixels per block,coding>
     (pixels per block is a even number in 2-32 and coding method is 'EC' or 'NN')
     Example of use:
     ./h5repack -i file1 -o file2 -f SZIP=8,NN -v

     updated usage messages, test scripts and files accordingly

#############################
Expected output for 'h5diff file1.h5 file2.h5 -n u g1/dset3 g1/dset4'
#############################
<-n u> is not a valid option
Usage: h5diff file1 file2 [OPTIONS] [obj1[obj2]]
file1 File name of the first HDF5 file
file2 File name of the second HDF5 file
[obj1] Name of an HDF5 object, in absolute path
[obj2] Name of an HDF5 object, in absolute path
[OPTIONS] are:
[-h] Print out this information
[-r] Report mode. Print the differences
[-v] Verbose mode. Print the differences, list of objects, warnings
[-q] Quiet mode. Do not do output
[-n count] Print difference up to count number
[-d delta] Print difference when it is greater than limit delta
[-p relative] Print difference when it is greater than a relative limit
Items in [] are optional
[obj1] and [obj2] are HDF5 objects (datasets, groups or datatypes)
The 'count' value must be a positive integer
The 'delta' and 'relative' values must be positive numbers
The -d compare criteria is |a - b| > delta
The -p compare criteria is |1 - b/a| > relative
h5diff has four modes of output:
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 (h5diff always returns an exit code of 1 when differences are found)
Examples of use:
1) h5diff file1 file2 /g1/dset1 /g1/dset2
Compares object '/g1/dset1' in file1 with '/g1/dset2' in file2
2) h5diff file1 file2 /g1/dset1
Compares object '/g1/dset1' in both files
3) h5diff file1 file2
Compares all objects in both files
Note) file1 and file2 can be the same file. Use
h5diff file1 file1 /g1/dset1 /g1/dset2
to compare '/g1/dset1' and '/g1/dset2' in the same file
