big testphdf5.c file. Broke it into modules of related routines.
testphdf5.c -- main routine and global variables initialization plus
some ulitility routines.
t_file.c -- tests of file operations using parallel I/O.
t_dset.c -- tests of datasets operations.

* This program contains two parts. In the first part, the mpi processes
|

* collectively create a new parallel HDF5 file and create two fixed
|
|
* dimension datasets in it. Then each process writes a hyperslab into
|
|
* each dataset in an independent mode. All processes collectively

* close the datasets and the file.
|
|
* In the second part, the processes collectively open the created file
|
|
* and the two datasets in it. Then each process reads a hyperslab from
|
|
* each dataset in an independent mode and prints them out.
|
|
* All processes collectively close the datasets and the file.
