/**
* The ResultSet class defines an object used for temporary storage of data. A ResultSet object is typically generated in a HandleTag; its data can then be displayed in a Web page that was defined by a converted HTML template.
*
* <p>Result sets need not be "regular" in shape. A result set can be as simple as one member that is a single text or numeric value. Or a result set can have several members, including one or more members that are lists or arrays. All members are created using one of two variations of the add() method:To add a simple (scalar) member to a result set, use the variation of the add() method with the rsMember parameter. For example:</p>
* <p><code>rset.add("announcement", new TextData("Hello World!"));</code></p>
* <p>To add a complex (list type) member to a result set, use the variation of the Add method with the listName parameter.</p>
