generate random numbers for 64-bit types while mitigating modulo bias
/*
`arc4random_uniform` is very useful but limited to `UInt32`.
This defines a generic version of `arc4random` for any type
expressible by an integer literal, and extends some numeric
types with a `random` method that mitigates for modulo bias
in the same manner as `arc4random`.
`lower` is inclusive and `upper` is exclusive, thus:

// For a contrived example, suppose we had a class like this with a queue:
import Foundation
