There are two variants of slugids:

The Slugid.v4() variant, which is a random UUID v4.
The Slugid.nice() variant, which is a random UUID v4 selected such that
the slugid encoding doesn't start with -.

The nice variant is nicer to use in commandline utilities, but it comes at a
slight cost in entropy. For more details refer to the
original implementation in javascript.
