This implements a variant of Format 1 from RFC 4122 that is intended to be roughly sortable and play nicely as Cassandra TimeUUID keys. Much of the inspiration comes form having used ryanking's simple_uuid gem.
As the package implies, this is a simple UUID generator. It doesn't offer total sorting, monotonic increments or prevent timing collisions.
This package does offer a simple combination of random and time based uniqueness that will play nicely if you want a unique key from a Time object. If your time objects sort with a granularity of 100 nanoseconds then the UUIDs generated will have the same order. UUIDs with the same time have undefined order.
The other formats described in RFC 4122 should be parsable either in text or byte form, though will not be sortable or likely have a meaningful time componenet.
