## Uuid
A class that generates RFC 4122 UUIDs. This specification defines a Uniform Resource Name namespace for UUIDs (Universally Unique IDentifier),
also known as GUIDs (Globally Unique IDentifier). A UUID is 128 bits long, and requires no central registration process.
Generating a UUID
```php
$uuid = Pimf\Util\Uuid::generate();
```
Yes, it is not the same UUID as generated before :-)
```php
Pimf\Util\Uuid::generate() !== Pimf\Util\Uuid::generate()
```
