Purpose:
    Add copyright and change "HDF5 Tutorial" link.
Description:
    Added copyright statement and link.
    Changed the "Tutorial" link to point to the copy on the HDF5 website.
        Since the Tutorial is not maintained in CVS, the distributed
        version of the Tutorial is being unlinked and removed from the
        set of distributed files. It is hoped that we can begin
        maintaining the Tutorial under CVS prior to Release 1.6 and
        resume its distribution.
Platforms tested:
    IE 5
