/*
Most basic example for the suggester for quick debugging.

This example doesn't check whether the input word is in the dictionary first.

## Usage

```
$ cargo run --example suggest ansi
Compiled the dictionary in 127ms
Suggestions for "ansi": "ANSI", "ans", "anti", "ans i" (checked in 1367µs)
```
