schism

Yeah, I couldn't follow the descriptions either. It looks like "list" only supports appending (conj), removing the first item (rest), and removing all items (empty). The data consists of a list of items, a "clock" (map of nodeId to Date object), and a list of (nodeId,Date) corresponding to the values. I think they're using the clock to determine whether to drop deleted items on merge. Code for the operations is [list.cljc:153-169](https://github.com/aredington/schism/blob/master/src/schism/...). The merge code is "synchronize" a little further down (I didn't read through it). The "vector" object supports append (conj), pop, clearing the list (empty), and setting a value at a position (assoc). It does _not_ support insert/delete. It is structured similarly to "list" except using vectors instead of lists for the values and the timestamps
