<h3>Total Control CRUD</h3>
This example is like <em>Easy CRUD</em> but shows how CRUD can be done "by hand", ie. without using Tapestry's Grid, BeanEditor, and BeanDisplay components.<br/>
For example, instead of using the Grid component we use the Loop and Output components in a normal HTML table.
