Classify a string as either English, Chinese, or Pinyin.
```rust extern crate chinese_detection;
use chinese_detection::ChineseDetection;
let language_detection = ChineseDetection::new();
println!("{}", languagedetection.classify(String::from("test"))); // --> EN println!("{}", languagedetection.classify(String::from*("shiyan"))); // --> PY println!("{}", language_detection.classify(String::from("实验"))); // --> ZH ```
