caves and cliffess

In the caves and cliffs first snapshot we saw a lot of new world generation and the 2nd snapshot we saw some new blocks and both snapshots have been added to the game within 14-17 days apart and it has been a while since the last one has been revealed and so I wanted to see some of the cave generation in the next snapshot to be released. If I were to choose I would add the large type of cave sense it is basically changing the cave size in generation in the code (easer said than done) but I think that would be the easiest feature to add next.
