``typeid(Representation)``
==========================

* ``Representation`` - Text representation for the TypeID, its type prefix, and its UUID suffix. Possible values are ``atom``, ``chars``, and ``codes``.


Type-safe, K-sortable, globally unique identifier (TypeID) generator. Implements the TypeID specification (a type prefix plus a version 7 UUID encoded using a strict, lowercase variant of Crockford base32).
