This isn't quite working to satisfy iProj3, but I need to get progress on iProj4 before this week actually starts.
oops...made lots of progress during the day and forgot to commit periodically...
A lot of progress with the file system. Time to nap.
You were right, I need to sleep.  File System mostly working, one issue I need a clear head to figure out.
I think the file system really works now, and the ls, too.
