README
Class to generate unique identifying strings. Largest attention is paid on human friendly unique identifiers (dated digits).
Supported UID Type
It supports several types of unique identifiers. The type you may want to use depends on how random and long you want the identifier to be. For most of the user cases a Micro UUID (20 chars) should be fine. A human UUID (32 chars) should almost never be used where a human is involved as too "mind bogling" to work with.
-
Human UUID (32 digits)
Format: YYYYMMDD-HHMM-SSMM-MMMMRRRRRRRRRRR

-
Nano UID (23 digits)
Format: YYYYMMDD-HHMMSS-MMMMMM-NNN
Examples:
