/**
 * Demonstrates the <code>FormLayout</code> with a <code>PanelBuilder</code>. 
 * Columns and rows are specified before the panel is filled with components.
 * Unlike the {@link PlainExample} this class uses a local variable
 * to keep track of the current row. The advantage over fixed numbers is, 
 * that it's easier to insert new rows later.<p>
 *  
 * This panel building style is simple and works quite well. However, you may
 * consider using a more sophisticated form builder to fill the panel and/or 
 * add rows dynamically; see the {@link DynamicRowsExample} for this alternative.
