//!
//! It's a port of the the parser from the Go standard library <https://github.com/golang/go/tree/release-branch.go1.12/src/go/parser>
//!  
//! # Usage:
//! ```
//! fn parse_file() {
//!     let source = "package main ...";
//!     let mut fs = go_parser::FileSet::new();
//!     let o = &mut go_parser::AstObjects::new();
//!     let el = &mut go_parser::ErrorList::new();
//!     let (p, _) = go_parser::parse_file(o, &mut fs, el, "./main.go", source, false);
//!     print!("{}", p.get_errors());
//! }
//! ```
//!
//! # Feature
//! - `btree_map`: Make it use BTreeMap instead of HashMap
//!
