[svn-r3560] tutorial

Purpose:
    [is this a bug fix? feature? ...]
Description:
    [describe the bug, or describe the new feature, etc]
Solution:
    [details about the changes, algorithm, etc...]
    [Please as detail as you can since your own explanation is
    better than others guessing it from the code.]
Platforms tested:
    [machines you have tested the changed version.  This is absolute
    important.  Test it out on at least two or three different platforms
    such as Big-endian-32bit (SUN/IRIX), little-endian-32(LINUX) and
    64-bit (IRIX64/UNICOS/DEC-ALPHA) would be good.]

+! The following example demonstrates how to create and close an HDF5 file.
+! It creates a file called 'file.h5',  and then closes the file.

+ 
+     INTEGER     ::   error  ! Error flag
+     
+!
+!    Initialize FORTRAN interface.
