SequentialGuid version 2, with IComparable and creation date and time

In an earlier post I compared the performance of Int (with autonumber) and a (Sequential) guid in SQL server. I posted an implementation of a C# SequentialGuid that created Guid's that were sequential, but they where still regular Guids. Once you had a Guid, it was just a regular Guid with the last 6 bytes ordered. The new version is a wrapper around the Guid with some cool extra stuff.
