Github repository

Not quite a full working version just yet, but I do have the code I've written so far posted on Github.

As of this writing, most of the abilities are to set up the unum environment, convert to and from reals, and to display unums in a human-readable fashion. I'm planning to get basic math implemented in the next few days. Then I should be able to do my first experiments, so looking forward to that.

On a more random note, I've learned a fair amount about how Fortran deals with number types. It's been interesting, and also extremely frustrating at times, but if it weren't then I probably wouldn't be learning anything, so there's that.
