"Provides a UUID v4 uuid generation.

In difference with builtin `random-uuid` function this

implementation tries to use high quality RNG if is

available (browser crypto object or nodejs crypto module).
|
|

If no high qualiry RNG, switches to the default Math based

RNG with proper waring in the console."
