//! # Introduction
//! The aim of this crate is to be a complete, idiomatic wrapper 
//! for the Entrez API.
//! 
//! The API is designed to be simple but at the same time,
//! flexible enough for advanced use cases.
//! 
//! # Usage
//! There are two categories of tools provided by this library:
//!  - *Wrappers* for the Entrez Eutilities.
//!  - *Parsers* to parse XML results obtained using the Eutilities.
//! ### Wrappers:
//! The [eutils] module contains the wrappers.
//! Currently available wrappers are:
//!  - [ESearch](eutils::ESearch)
//!  - [EFetch](eutils::EFetch) 
//! 
//! ### Parsers:
//! The [parser] module contains the parsers.
//! Currently available parsers are:
//!  - [esearch](parser::esearch)
//!  - [pubmed](parser::pubmed)
