THIS IS A UNIT CURRENTLY UNDER DEVELOPEMENT

      Current Functionality
          - Text support (inc Tabs and CRs)
          - Paragraph/Character Style Support
          - Supports Section Breaks (via PageSequences)
          - Supports Header and Footer
          - Supports Portrait/Landscape
          - Support Tables

      TODO
          - Add following to both FPVectorial AND DOCXWriter
            - Add Image Support (From file and from Stream, in Paragraph and in Table)
            - Add simple Work Fields (NumPage, PageCount, Filename (Full, part), DatePrinted)
            - Add TOC support
            - Consider Unicode Support (eek)

Writes an OOXML (Office Open XML) document

An OOXML document is a compressed ZIP file with the following files inside:

  [Content_Types].xml          - An index of all files, defines their content format
  _rels\.rels                  - Relationships between high level documents
  word\_rels\document.xml.rels - defines relationships to files required by document.xml (ie styles.xml)
  word\document.xml            - this is the main document.  Conforms to WordprocessingML
  word\styles.xml              - The Style Library
  word\header%d.xml            - One file per header
  word\footer%d.xml            - One file per footer
  word\numbering.xml           - Header and List numbering details
  media\*.[png, jpg, etc]      - Images

AUTHORS: Mike Thompson, Felipe Monteiro de Carvalho

Change History
 0.1 - minimal document.xml produced
     - experimental support for styles (not working, hidden behind INCLUDE_STYLES define)
 0.2 - Refactored for new VectorialElement TvParagraph
     - Removed INCLUDE_STYLES define
     - Added support for Styles - resulting .docx contains ONLY styles defined in VectorialDocument
       Only Paragraph Style supported for now
     - Added IndentedStringList simply to prettify the resulting XML
 0.3 - Added support for Character Styles (named TextSpan Styles within FPVectorial
     - If Style.Name not defined, then create one based on index
     - Refactored PrepareTextRunStyle out of Prepare Styles.  Resulting XML is perfectly valid
       inside Document.XML and Style.xml, though FPVectorial currently does not support this
     - Closed out minor TODO items
 0.4 - realised <>'"& would break the resulting XML.  Added EscapeHTML when
       User defined text is outputted into the HTML
     - Multiple PageSequences are now handled.
     - Added support for Portrait/Landscape (reverse Width/Height if you want Landscape)
     - Added generic support for multiple files.  Link IDs and Relationships between
       Files are automatically handled.  Currently works for XML files only
       but should be easily extended for Image Support (code tagged with TODO)
     - Added support for Header and Footer.  Can be defined per PageSequence resulting
       in multiple headers and footers or just on the first PageSequence
       (in which case the rest of the document will inherit the same Header / Footer)
       Couldn't get the inline Header/Footers to work, so implemented as separate files.
     - Added handling for #11 (tab), #10 (line feed), #13 (CR) and #13#10 in Text Support
     - Significant refactoring of code, and formatted code with Jedi Code Format.
       I intend to Jedi Code Format before each Patch from here on
     - Added support for Alignment to Styles
 0.5 - Support TvParagraph margins
     - Added numbering.xml
 0.6 - Changed #11 (vert tab) to #09 (horiz tab, what it always should have been)
     - Added Table Support
     - Bug fix - Margin support in Styles fixed...
 0.7 - Added experimental LocalAlignment support to TvParagraph
