About combine

An implementation of parser combinators for Rust, inspired by the Haskell library Parsec. As in Parsec the parsers are LL(1) by default but they can opt-in to arbitrary lookahead using the attempt combinator. Example

```rust extern crate combine; use combine::{many1, Parser, sepby}; use combine::{letter, space};

// Construct a parser that parses many (and at least 1) letters let word = many1(letter());
