//! This crate contains two types: `Teddy` is the main one. You create one by passing in a set of
//! patterns. It does some preprocessing, and then you can use it to quickly search for those
//! patterns in some text. Searching returns a `Match`, which will tell you which of the patterns
//! matched and where.
//!
//! ```
//! use teddy::{Match, Teddy};
//!
//! let patterns = vec![b"cat", b"dog", b"fox"];
//! let ted = Teddy::new(patterns.iter().map(|s| &s[..])).unwrap();
//! assert_eq!(
//!     Some(Match { pat: 2, start: 16, end: 19 }),
//!     ted.find(b"The quick brown fox jumped over the laxy dog.")
//! );
//! ```
