//! Wrapper around PathBuf to provide extra features for popping,
//! pushing, indexing and generally manipulation of paths. All the same
//! conversions and method signatures, making `SmartPathBuf`
//!  isomorphic to `PathBuf`. It implements `Deref` with 
//! `Target` `Path` so all of paths functionality is available.
//!
//! ## Examples where useful
//! ```
//! use smart_path::SmartPathBuf;
//!
//! let dir = std::env::current_dir().expect("failed");
//! let mut s_path = SmartPathBuf::from(&dir);
//! 
//! s_path.push("to/file");
//! // do_something(&s_path); // "current/dir/to/file"
//! 
//! s_path.initial();
//! // "current/dir"
//! 
//! s_path.push("another/file");
//! // do_more(&s_path);
//! ```
//!

pub use s_path_buf::{PathRange, SmartPathBuf};
