Represents a UUID. A UUID (Universally Unique Identifier) or GUID (Globally Unique Identifier) is a generated value guaranteed to be unique across all computers and databases. UUIDs are stored as SQLType.BINARY(16) values in UltraLite databases and can be used to uniquely identify rows. The UUID class stores immutable UUIDs.

A UUID is associated with the Connection that created it and can no longer be converted to a string after the connection is closed.
