Class GUID
A globally-unique identifier made up of time and ip and 3 random
digits: 35 characters wide A globally unique identifier that combines ip,
time, and random bits. Since the time is listed first, you can sort
records by guid. You can also extract the time and ip if needed.
GUIDs make wonderful database keys. They require no access to the
database (to get the max index number), they are extremely unique, and
they sort automatically by time. GUIDs prevent key clashes when merging
two databases together, combining data, or generating keys in distributed
systems.

| |
random(self)
Extracts the random bits from the guid. |

__init__(self,

(Constructor)
Constructor. Use no args if you want the guid generated (this is the
normal method) or send a string-typed guid to generate it from the
string
