Purpose:
Adding F90 || tests.
Description:
I created testpar directory with the following files
ptesthdf5_fortran.f90 - F90 test driver program
tcheck.f90 thdf5.f90 - handy subroutines to use with the tests
thyperslab_wr.f90 - F90 test:
collectively writes and reads hyperslabs to/from the dataset
Solution:
Platforms tested:
Partially tested on modi4 (O2K)
