 * A Chapter is a special Section.

 * A chapter number has to be created using a Paragraph as title
 * and an int as chapter number. The chapter number is shown be
 * default. If you don't want to see the chapter number, you have to set the
 * numberdepth to 0.
 * 

 * Example:
 * 
 * Paragraph title2 = new Paragraph("This is Chapter 2", FontFactory.getFont(FontFactory.HELVETICA, 18, Font.BOLDITALIC, new Color(0, 0, 255)));
 * Chapter chapter2 = new Chapter(title2, 2);
 * chapter2.setNumberDepth(0);
 * Paragraph someText = new Paragraph("This is some text");
 * chapter2.add(someText);
 * Paragraph title21 = new Paragraph("This is Section 1 in Chapter 2", FontFactory.getFont(FontFactory.HELVETICA, 16, Font.BOLD, new Color(255, 0, 0)));
 * Section section1 = chapter2.addSection(title21);
 * Paragraph someSectionText = new Paragraph("This is some silly paragraph in a chapter and/or section. It contains some text to test the functionality of Chapters and Section.");
 * section1.add(someSectionText);
