Like node's Abbrev module
```rust use abbrev::abbrev;
fn main() { let xs = vec!["foo", "fool", "folding", "flop"]; let map = abbrev(&xs);
println!("{:#?}", map);
} ```
And it will print:
json
{
"fl": "flop",
"flo": "flop",
"flop": "flop",
"fol": "folding",
"fold": "folding",
"foldi": "folding",
"foldin": "folding",
"folding": "folding",
"foo": "foo",
"fool": "fool"
}
