/**
 * A ListItem is a Paragraph
 * that can be added to a List.
 * 
 * Example 1:
 * 
 * List list = new List(true, 20);
 * list.add(new ListItem("First line"));
 * list.add(new ListItem("The second line is longer to see what happens once the end of the line is reached. Will it start on a new line?"));
 * list.add(new ListItem("Third line"));
 * 
 *
 * The result of this code looks like this:
 *	
 *		
 *			First line
 *		
 *		
 *			The second line is longer to see what happens once the end of the line is reached. Will it start on a new line?
 *		
 *		
 *			Third line
 *		
 *	
 *
 * Example 2:
 *  * List overview = new List(false, 10);
 * overview.add(new ListItem("This is an item"));
 * overview.add("This is another item");
 * 
 *
 * The result of this code looks like this:
 *	
 *		
 *			This is an item
 *		
 *		
 *			This is another item
 *		
 *
