/**
* A Section is a part of a Document containing
* other Sections, Paragraphs, List
* and/or Tables.
*
* Remark: you can not construct a Section yourself.
* You will have to ask an instance of Section to the
* Chapter or Section to which you want to
* add the new Section.
*
* 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);
* 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);
* Paragraph title211 = new Paragraph("This is SubSection 1 in Section 1 in Chapter 2", FontFactory.getFont(FontFactory.HELVETICA, 14, Font.BOLD, new Color(255, 0, 0)));
* Section section11 = section1.addSection(40, title211, 2);
