new Imath repo

Cary Phillips

We had an unexpected delay in getting the ASWF Imath repo created, but it's in place now:

Thanks to Owen, it preserves the proper file revision history, and it builds, too. There's also a separate repo for PyImath:

I set up a GitHub project to track progress using GitHub Issues.  If you're interested in contributing to the discussion about further developments with Imath, please subscribe to notifications from the GitHub repo, and comment freely on the issues or file new ones as you think of things you'd like to discuss or propose.
