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

extern crate bincode;
