I'm feeling much better than I have been. The mucus factory is pretty much closed. However, I seem to need to drink a heroic amount of water. I constantly feel parched. Must be the wintry weather.
It's still very nasty outside. I'm spending an awful amount of time inside for a Montana boy. Then again, I am getting over an illness and I'm getting pleny of work done.
Speaking of work, I didn't find much to help me with my hash tree problem. I found plenty of stuff about traversal and general graph theory but nothing that specifically helps me.
I think it boils down to doing a traversal. I have to run down the tree until I hit the bottom of a branch, check to see if that child is holding any data, if not delete it. Then go up to the parent of that child, if the parent has no children, then delete it. This goes on until have traversed the whole tree/hash.
Maybe I'll do some more research.
