DocWriter class for HTML.
*
* An HtmlWriter can be added as a DocListener
* to a certain Document by getting an instance.
* Every Element added to the original Document
* will be written to the Stream of this HtmlWriter.
*
* Example: *
* // creation of the document with a certain size and certain margins
* Document document = new Document(PageSize.A4, 50, 50, 50, 50);
* try {
* // this will write HTML to the Standard Stream
* HtmlWriter.GetInstance(document, System.out);
* // this will write HTML to a file called text.html
* HtmlWriter.GetInstance(document, new FileOutputStream("text.html"));
* // this will write HTML to for instance the Stream of a HttpServletResponse-object
* HtmlWriter.GetInstance(document, response.GetOutputStream());
* }
* catch (DocumentException de) {
* System.err.Println(de.GetMessage());
* }
* // this will close the document and all the OutputStreams listening to it
* document.Close();
* HtmlWriter.
*
* @param doc The Document that has to be written as HTML
* @param os The Stream the writer has to write to.
