 * Use this class ONLY inside Paragraph in order to format pieces of a paragraph.
 * for example, if you want to make one and only one word of the paragraph bold.
 * ALWAYS USE THIS CLASS INSIDE A PARAGRAPH. OTHERWISE WON'T WORK. This is the way you should use it:
 * <pre>
 * myDoc.addEle(Paragraph.withPieces(ParagraphPiece.with("This is one piece.").create()));
 * </pre>
 * NEVER LIKE THIS:
 * <pre>
 * myDoc.addEle(ParagraphPiece.with("This is one piece.").create());
 * </pre>
