* <BLOCKQUOTE><PRE>
* List list = new List(true, 20);
* list.add(<STRONG>new ListItem("First line")</STRONG>);

*
* The result of this code looks like this:

* </LI>
* <LI>
* The second line is longer to see what happens once the end of the line is reached. Will it start on a new line?
* </LI>

* <B>Example 2:</B>
* <BLOCKQUOTE><PRE>
* List overview = new List(false, 10);
* overview.add(<STRONG>new ListItem("This is an item")</STRONG>);
* overview.add("This is another item");
* </PRE></BLOCKQUOTE>
*
* The result of this code looks like this:
* <UL>
* <LI>
* This is an item
* </LI>
* <LI>
* This is another item
* </LI>
* </UL>
