/**
* Guid represents a UUID with "native" (little-endian) byte order
*
* From Wikipedia:
*
* > The first three fields are unsigned 32- and 16-bit integers and are subject
* > to swapping, while the last two fields consist of uninterpreted bytes, not
* > subject to swapping. This byte swapping applies even for versions 3, 4, and
* > 5, where the canonical fields do not correspond to the content of the UUID.
*
* The first three fields of a GUID are encoded in little-endian byte order,
* while the last three fields are in network (big-endian) byte order. This is
* according to the history of the Microsoft definition of a GUID.
*
* According to the .NET Guid.ToByteArray method documentation:
*
* > Note that the order of bytes in the returned byte array is different from
* > the string representation of a Guid value. The order of the beginning
* > four-byte group and the next two two-byte groups is reversed, whereas the
* > order of the last two-byte group and the closing six-byte group is the
* > same.
