[Hallcsw] Move to Github to story repositories

[Mark Jones]

We are moving the hcana git repository to GitHub . This will
allow us to take advantage of the tools at GitHub and to
easily share the code with offsite users.

Steve has written a new set of instructions for getting
the hcana repo and making contributions to the code.
Go to the link:

If there are porblems or suggestions please let Steve or I know.

            Cheers,
                    Mark
