/**
* 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
*
