> Since the switch to typed column names and CompareSubcolumnsWith we no longer
> have a simple way to order entries in a super column / column family by their
> creation time. This makes things like 'timelines' harder to implement.
> After discussions on IRC / twitter it appears we could achieve this with a
> new comparator for UUIDTypes which checks their temporal order before just
> falling back on their lexical order.
