weightedrandomlist

A Vec that allows you to define the weight of each entry and randomly get entries:

```rust extern crate weightedrandomlist;

use weightedrandomlist::WeightedRandomList;

fn main() { let list = [ (1, "https://source.example.net/archive"), (10, "https://mirror-slow0.example.net/archive"), (10, "https://mirror-slow1.example.net/archive"), (100, "https://mirror-fast.example.net/archive"), ];

let mirrors = list.iter()
        .map(|(weight, url)| (*weight, url.to_string()))
        .collect::<WeightedRandomList<String>>();


let random_choice = mirrors.get_random();
println!("Using {:?} this time", random_choice);

} ```
