An Implementation Class that will retrieve a valid new value
for a PK field that is of type 'uniqueidentifier'. Since values
for these types are generated through a 'newid()' call to
MSSQL Server, this class is only valid for MSSQL Server 7.0 and up.
This SequenceManager can be used for any classes that have their PK
defined as a 'uniqueidetifier'
