#![allow(clippy::unwrap_used)]
//! <sheet name="Sheet1" sheetId="1" r:id="rId1"/>

//! A workbook is composed of workbook-level properties and a collection of 1 or more sheets.
//! The workbook part and corresponding properties comprise data
//! used to set application and workbook-level operational state. The workbook also serves to bind all the sheets
//! and child elements into an organized single file. The workbook XML attributes and elements include information
//! about what application last saved the file, where and how the windows of the workbook were positioned, and
//! an enumeration of the worksheets in the workbook.
//! This is the XML for the smallest possible (blank) workbook:
//!
//! <workbook>
//!   <sheets>
//!     <sheet name="Sheet1" sheetId="1" r:id="rId1"/>
//!   </sheets>
//! </workbook>
//!
//! Note that this workbook has a single sheet, named Sheet1. An Id for the sheet is required, and a relationship Id
//! pointing to the location of the sheet definition is also required.
//!
//!
//!
//! The most important objet of this part is a collection of all the sheets and all the defined names
//! of the workbook.
//!
//! It also may hold state properties like the selected tab

//! # bookViews
//!
