-- Creates a new uuid. Either provide a unique hex string, or make sure the\\\

--\\\
-- For proper use there are 3 options;\\\
--\\\
-- 1. first require `luasocket`, then call `uuid.seed()`, and request a uuid using no \\\
-- parameter, eg. `my_uuid = uuid()`\\\
-- 2. use `uuid` without `luasocket`, set a random seed using `uuid.randomseed(some_good_seed)`, \\\
-- and request a uuid using no parameter, eg. `my_uuid = uuid()`\\\
-- 3. use `uuid` without `luasocket`, and request a uuid using an unique hex string, \\\
-- eg. `my_uuid = uuid(my_networkcard_macaddress)`\\\
