First Release

Thanks for considering dyn_path for your project, to download it please, use cargo add dyn_path in your root project directory.

This release brings two macros with it, the dyn_access macro which generates .and_then(|v| v.get()) in a nested way for nested structures such as JSON de-serialization with serde_json. The second macro this brings uses the same syntaxis as dyn_access except it's only for displaying and computing paths, so you can describe errors in an easier way.
