com.lowagie.text.Paragraph
A Paragraph is a series of Chunks and/or Phrases.
A Paragraph has the same qualities of a Phrase, but also some additional layout-parameters:
- the indentation
- the alignment of the text
Example:
```
 Paragraph p = new Paragraph("This is a paragraph", FontFactory.getFont(FontFactory.HELVETICA, 18, Font.BOLDITALIC, new Color(0, 0, 255))); 
```
@see Element @see Phrase @see ListItem
