RingBuffer is now SharedCore. I think that's all the container classes, there
may be a few other things that should change too, we'll see. Played with doxygen docs on List, we can actually use @cond to remove things from the docs, either permenently or conditionally, and so I could trick it into making all of the sharedcore classes inherit from the same SharedCore in the docs instead of different ones. Or, just not inherit from SharedCore at all. What to do...? :-P I also got rid of ListHash, it wasn't working out yet anyway.
