    """
    A class for writing the Excel XLSX Packager file.

    This module is used in conjunction with XlsxWriter to create an
    Excel XLSX container file.

    From Wikipedia: The Open Packaging Conventions (OPC) is a
    container-file technology initially created by Microsoft to store
    a combination of XML and non-XML files that together form a single
    entity such as an Open XML Paper Specification (OpenXPS)
    document. http://en.wikipedia.org/wiki/Open_Packaging_Conventions.

    At its simplest an Excel XLSX file contains the following elements::

         ____ [Content_Types].xml
        |
        |____ docProps
        | |____ app.xml
        | |____ core.xml
        |
        |____ xl
        | |____ workbook.xml
        | |____ worksheets
        | | |____ sheet1.xml
        | |
        | |____ styles.xml
        | |
        | |____ theme
        | | |____ theme1.xml
        | |
        | |_____rels
        | |____ workbook.xml.rels
        |
        |_____rels
          |____ .rels

    The Packager class coordinates the classes that represent the
    elements of the package and writes them into the XLSX file.
