Code mapping utility types and traits.

This library provides essentials types and trait to locate syntax elements.

• Span describes a byte range in a source file. It is very similar to Range<usize> but is not an iterator and implements Copy. It also provides an intuitive API to write lexers and parsers.
• Location<F> combines a Span with a file identifier F to pin point a syntactic element in a source file.

The crate integrates well with codespan-reporting library to render beautiful error reports. Enable the reporting feature to add dedicated methods to convert a Location value into a codespan_reporting::diagnostic::Label.
